Description
Oppfinnelsen vedrører nye 1,1-ditienyl-(3)-1-hydroksy-alkyl-halogenider med den generelle formel The invention relates to new 1,1-dithienyl-(3)-1-hydroxy-alkyl halides with the general formula
hvori Alk betyr en rettlinjet eller forgrenet C^-C^-alkylengruppe og X betyr klor, brom eller jod samt en fremgangsmåte til deres fremstilling. De nye forbindelser med den generelle formel I fåes ifølge oppfinnelsen ved omsetning av tienyl-(3)- eller tienyl-(2)-litium med en forbindelse med den generelle formel hvori Alk betyr en rettlinjet eller forgrenet C^-C^-alkylengruppe, fortrinnsvis en rettlinjet C^-C^-alkylengruppe, Z betyr en lavere alkoksygruppe, klor, brom, jod eller en tienyl-(3)-rest eller en tienyl-(2)-rest og Hal er klor, brom eller jod ved lave temperaturer, fortrinnsvis under -50°Ci i et inert middel. Herved oppstår forbindelsen med formel I i et utbytte på eksempelvis 96% av det teore-tiske . in which Alk means a straight or branched C 1 -C 2 -alkylene group and X means chlorine, bromine or iodine and a method for their preparation. The new compounds with the general formula I are obtained according to the invention by reacting thienyl-(3)- or thienyl-(2)-lithium with a compound of the general formula in which Alk means a straight or branched C₁-C₂ alkylene group, preferably a linear C₁-C₁ alkylene group, Z means a lower alkoxy group, chlorine, bromine, iodine or a thienyl-(3) residue or a thienyl-(2) residue and Hal is chlorine, bromine or iodine at low temperatures, preferably below -50°Ci in an inert agent. Hereby, the compound with formula I is produced in a yield of, for example, 96% of the theoretical.
De hittil kjente analoge omsetninger, eksempelvis av tienyl-(3)-litium med o>-fenyletylamino-propionsyreestere (se tysk patent 1 921 453) forløper derimot ikke enhetlig og den ønskede ditienyl-(3)-forbindelse kan bare isoleres i utbytter på maksimalt 30%. Spesielt oppstår herved alltid andre tienyl-isomere i større mengder. Dessuten er adskillelsen og resning av den ønskede ditienyl-forbindelse fra de øvrige reaksjonsprodukter meget vanskelig, og eksempelvis bare mulig ved omstendelig og flere gangers omkrystallisering i kombina-sjon med en aktivkullbehandling. The previously known analogous reactions, for example of thienyl-(3)-lithium with o>-phenylethylamino-propionic acid esters (see German patent 1 921 453), on the other hand, do not proceed uniformly and the desired dithienyl-(3)-compound can only be isolated in yields of maximum 30%. In particular, other thienyl isomers always occur in larger amounts. Moreover, the separation and recovery of the desired dithienyl compound from the other reaction products is very difficult, and for example only possible by extensive and repeated recrystallization in combination with an activated carbon treatment.
I den generelle formel II betyr resten Z spesielt en mettet alifatisk alkoksygruppe med 1-6 C-atomer, fortrinnsvis 1-4 C-atomer, som også kan være forgrenet, klor eller brom. Z kan imidlertid også være en tienyl-(2)-rest eller en tienyl-(3)-rest. In the general formula II, the radical Z means in particular a saturated aliphatic alkoxy group with 1-6 C atoms, preferably 1-4 C atoms, which may also be branched, chlorine or bromine. However, Z can also be a thienyl-(2) residue or a thienyl-(3) residue.
Omsetningen av tienyllitium-forbindelsen, spesielt av tienyl-(3)-litium med forbindelsen II, foregår i en inert flytende oppløsningsmiddelblanding som fortrinnsvis består av en mettet eter og et mettet hydrokarbon og/eller med C-^-C-j-mono- eller dialkylrester substituert benzen. Som halogen-C2~Cg-alkankarboksylsyreestere kommer det eksempelvis på tale: 3-halogen-propionsyreester, -smørsyreester eller -valeriansyreester. The reaction of the thienyllithium compound, especially of thienyl-(3)-lithium with the compound II, takes place in an inert liquid solvent mixture which preferably consists of a saturated ether and a saturated hydrocarbon and/or with C-^-C-j-mono- or dialkyl radicals substituted benzene. Halogen-C2~Cg-alkanecarboxylic acid esters include, for example: 3-halo-propionic acid ester, -butyric acid ester or -valeric acid ester.
Består oppløsningsmiddelblandingen av en eter og mettet hydrokarbon, så anvendes eksempelvis på en volumdel hydrokarbon 0,3-3, fortrinnsvis 0,8-3 volumdeler eter. For en oppløsningsmiddelblanding av eter og mono- eller dialkylben-zen gjelder eksempelvis pr. 1 volumdel alkylbenzen 0,1-3, fortrinnsvis 0,2-1 volumdeler eter. Består oppløsnings-middelblandingen av de tre komponenter: eter, mettet hydrokarbon og alkylbenzen, da er eksempelvis blandingsforholdet av de tre komponenter eter:hydrokarbon:benzen = 0,1-0,9: 0,1-0,9:0,1-0,9. Som mettet eter kommer det spesielt på tale alifatiske symmetriske eller usymmetriske dialkyleter, idet alkylgruppene fortrinnsvis består av 1-6 C-atomer, If the solvent mixture consists of an ether and saturated hydrocarbon, then 0.3-3, preferably 0.8-3, parts by volume of ether are used, for example, per volume of hydrocarbon. For a solvent mixture of ether and mono- or dialkylbenzene applies, for example, per 1 volume part alkylbenzene 0.1-3, preferably 0.2-1 volume parts ether. If the solvent mixture consists of the three components: ether, saturated hydrocarbon and alkylbenzene, then for example the mixing ratio of the three components is ether:hydrocarbon:benzene = 0.1-0.9: 0.1-0.9:0.1- 0.9. Saturated ethers are particularly aliphatic symmetrical or unsymmetrical dialkyl ethers, the alkyl groups preferably consisting of 1-6 C atoms,
og eksempelvis er metyl, etyl, isopropyl, propyl, isobutyl eller butyl. Videre kommer det som eter eksempelvis også and examples are methyl, ethyl, isopropyl, propyl, isobutyl or butyl. Furthermore, things like ether also come, for example
i betraktning C^-Cg-alkyleter av mettede cykloalkanoler og considering C^-Cg alkyl ethers of saturated cycloalkanols and
alkylsubstituerte cykloalkanoler, idet cykloalkanolringen hver gang består av 3, 4, 5 eller 6 C-atomer. Fortrinnsvis er eterene flytende i området mellom -80 og +20°C. alkyl-substituted cycloalkanols, the cycloalkanol ring each time consisting of 3, 4, 5 or 6 C atoms. Preferably, the ethers are liquid in the range between -80 and +20°C.
Ved de mettede hydrokarboner dreier det seg om alifatiske eller cykloalifatiske hydrokarboner som er flytende i tempera-turområdet mellom -80 og +20°C, og eksempelvis har 5-9, fortrinnsvis 6-7 C-atomer og også kan være forgrenet. De cykloalifatiske hydrokarboner er fortrinnsvis substituert en eller også flere ganger (2 ganger, 3 ganger) med C-^-C^-alkylrester, spesielt metyl-, etyl- eller propylrester, idet antallet ringatomer kan være 3, 4, 5, 6 eller 7. De mettede alkyl-rester som kommer på tale som substituenter for benzen er metyl, etyl, propyl, isopropyl, butyl, isobutyl, tert.-butyl, 1-metylpropyl. The saturated hydrocarbons are aliphatic or cycloaliphatic hydrocarbons which are liquid in the temperature range between -80 and +20°C, and for example have 5-9, preferably 6-7 C atoms and can also be branched. The cycloaliphatic hydrocarbons are preferably substituted one or more times (2 times, 3 times) with C-^-C^-alkyl residues, especially methyl, ethyl or propyl residues, the number of ring atoms being 3, 4, 5, 6 or 7. The saturated alkyl residues that come into question as substituents for benzene are methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert-butyl, 1-methylpropyl.
Eksempler for de angjeldende oppløsningsmidler er: dietyleter, diisopropyleter, metylcyklopentyleter, heksan, cykloheksan, toluen, xylen, metylcykloheksan, metylcyklopentan, etyl-cykloheksan, dimetylcykloheksan. Examples of the relevant solvents are: diethyl ether, diisopropyl ether, methylcyclopentyl ether, hexane, cyclohexane, toluene, xylene, methylcyclohexane, methylcyclopentane, ethylcyclohexane, dimethylcyclohexane.
Det er fordelaktig når forbindelsen II, spesielt når det dreier seg om 8-halogen-alkankarboksylsyreestere, tildoseres som sådanne eller i form av en oppløsning i hydrokarbonet og/eller eter (eksempelvis diisopropyleter og/eller toluen) til den til reaksjonstemperatur foravkjølte tienyllitium It is advantageous when the compound II, especially when it concerns 8-halo-alkanecarboxylic acid esters, is added as such or in the form of a solution in the hydrocarbon and/or ether (for example diisopropyl ether and/or toluene) to the thienyllithium precooled to reaction temperature
(som tienyl-(3)-litium) og deretter holdes reaksjonsblandingen enda i 1-4 timer ved reaksjonstemperatur. Deretter blandes eksempelvis reaksjonsoppløsningen med vann, eventuelt etter oppvarming til -20 til +20°C. Den organiske fase tørkes (MgSO^, Na2SO^) og inndampes under nedsatt trykk. Det således dannede rå 1,1-bis-[tienyl- (3 eller 2)]-3-halogen-alkanol kan anvendes uten ytterligere rensing for omsetningen med eksempelvis aminer. Tienyllitium-forbindelsene, eksempelvis tienyl-(3 eller 2)-litium, fremstilles vanligvis hver gang på forhånd av 3-brom- eller 2-brom-tiofen eller 3-jod-resp. 2-jod-tiofen i eteren og en C-^-C^-alkyllitium- eller (as thienyl-(3)-lithium) and then the reaction mixture is kept for a further 1-4 hours at the reaction temperature. Then, for example, the reaction solution is mixed with water, optionally after heating to -20 to +20°C. The organic phase is dried (MgSO^, Na2SO^) and evaporated under reduced pressure. The crude 1,1-bis-[thienyl-(3 or 2)]-3-haloalkanol thus formed can be used without further purification for the reaction with, for example, amines. The thienyllithium compounds, for example thienyl-(3 or 2)-lithium, are usually prepared each time in advance from 3-bromo- or 2-bromo-thiophene or 3-iodo-resp. 2-iodo-thiophene in the ether and a C-^-C^-alkyllithium or
aryllitium-forbindelse i eter-hydrokarbon-blåndingen, idet det som eter og hydrokarboner (innbefattende alkylbenzener) kommer på tale det allerede nevnte (som eter, spesielt dialkyleter).Alkylresten av alkyllitium-forbindelsen kan være rettlinjet eller forgrenet. Eksempeler er: butyllitium, sec.-butyllitium, tert.-butyllitium, metyllitium, etyllitium, fenyllitium, naftyllitium. aryllithium compound in the ether-hydrocarbon mixture, as ether and hydrocarbons (including alkylbenzenes) are those already mentioned (as ether, especially dialkylether). The alkyl residue of the alkyllithium compound can be linear or branched. Examples are: butyllithium, sec.-butyllithium, tert.-butyllithium, methyllithium, ethyllithium, phenyllithium, naphthyllithium.

i det eventuelle oppløsningsmiddel ligger eksempelvis mellom 5 og 30 vekt-%. Konsentrasjonen av brom-tiofenet eller jod-tiofenet i det eventuelle oppløsningsmiddel ligger eksempelvis mellom 10 og 100 vekt-%. in the possible solvent is, for example, between 5 and 30% by weight. The concentration of bromo-thiophene or iodo-thiophene in the possible solvent is, for example, between 10 and 100% by weight.
Vanligvis går man fram således at brom- eller jod-tiofenet inndoseres som sådant eller i form av en oppløsning i eteren eller flytende alifatisk hydrokarbon eller alkylbenzen til litiumalkyl eller litiumaryl, som er oppløst resp. suspen-dert i en av d e nevnte etere eller en blanding av eter og alifatisk hydrokarbon (forhold 1-1,5:1) eller eter og alkylbenzen (forhold 0,2-0,5:1) (konsentrasjon av litium-forbindelsen mellom 5 og 30 vekt-%) og er avkjølt til temperaturer under -70°C, således at temperaturen ikke øker over -70°C. Reaksjonskomponentene med formel II tilsettes da eksempelvis Usually, the procedure is such that the bromo- or iodo-thiophene is dosed as such or in the form of a solution in the ether or liquid aliphatic hydrocarbon or alkylbenzene to lithium alkyl or lithium aryl, which is dissolved resp. suspended in one of the aforementioned ethers or a mixture of ether and aliphatic hydrocarbon (ratio 1-1.5:1) or ether and alkylbenzene (ratio 0.2-0.5:1) (concentration of the lithium compound between 5 and 30% by weight and is cooled to temperatures below -70°C, so that the temperature does not rise above -70°C. The reaction components with formula II are then added, for example
i form av en 10-100%-ig oppløsning (vekt-%) i en som allerede angitt dialkyleter eller alkylbenzen, likeledes således at temperaturen ikke øker over -70°C. in the form of a 10-100% solution (% by weight) in one of the already mentioned dialkyl ethers or alkylbenzene, likewise so that the temperature does not rise above -70°C.
I. en foretrukket utførelsesform av fremgangsmåten ifølge oppfinnelsen gjennomføres reaksjonen i en oppløsningsmiddelbland-ing av toluen og diisopropyleter og etter hydrolyse av reaksjonsblandingen underkastes den organiske fase en fraksjonert vakuumdestillasjon, idet oventil fjernes de lettkokende deler av blandingen som eksempelvis diisopropyleter, tiofen, butyl-bromid og andre samt en del av det anvendte toluen og som sumpresidu fåes oppløsning av 1,1-bis-[tienyl-(3)- og/eller In a preferred embodiment of the method according to the invention, the reaction is carried out in a solvent mixture of toluene and diisopropyl ether and, after hydrolysis of the reaction mixture, the organic phase is subjected to a fractional vacuum distillation, the high-boiling parts of the mixture being removed above, such as diisopropyl ether, thiophene, butyl bromide and others as well as part of the toluene used and as sum residue a solution of 1,1-bis-[thienyl-(3)- and/or
-tienyl-(2) -w-halogen-alkanol i toluen som direkte anvendes-thienyl-(2)-w-halo-alkanol in toluene which is directly used
i fremgangsmåtens neste trinn.in the next step of the procedure.
Reaksjonsdeltagerne kan eksempelvis anvendes i følgende molforhold: tieny 1--litium: forbindelse (II) = 2,0-4,0:1. The reaction participants can, for example, be used in the following molar ratio: tieny 1--lithium: compound (II) = 2.0-4.0:1.
Refererer man til litiumalkyl og brom- eller jodtiofen, så kommer eksempelvis følgende molforhold på tale: alkyllitium-forbindelse: brom- eller jodtiofen:forbindelse (II) = 2,5-5,0: 2,0-4,0:1, spesielt 2,0-5,0:2,0-4,0:1. If one refers to lithium alkyl and bromo- or iodothiophene, the following molar ratio is used, for example: alkyllithium compound: bromo- or iodothiophene: compound (II) = 2.5-5.0: 2.0-4.0:1, especially 2.0-5.0:2.0-4.0:1.
Reaksjonstemperaturen bør eksempelvis ikke overstige -50°C, fortrinnsvis er gjennomføring av reaksjonen eksempelvis ved temperaturer mellom -65 og-75°C. Fortrinnsvis overholdes en temperatur under -70°C, eksempelvis -80 og -70°C. The reaction temperature should not, for example, exceed -50°C, preferably carrying out the reaction at temperatures between -65 and -75°C, for example. A temperature below -70°C is preferably observed, for example -80 and -70°C.
Den dannede 1,1-bis-[ tienyl-( 3 og/eller 2) ]-co-halogen-alkanol med formel I kan omsettes direkte uten ytterligere rensing med aminer. Denne omsetning kan foregå med eller uten oppløsnings- resp. suspensjonsmiddel. Som inert opp-løsnings- eller suspensjonsmidler egner det seg eksempelvis de samme midler som kommer på tale for reaksjonsen av tienyllitium med forbindelse II, eksempelvis diisopropyleter, toluen og lignende. Dessuten kan eksempelvis også anvendes andre alkyl- og dialkylbenzener, dialkyleter, alifatiske ketoner og alifatiske og cykloalifatiske alkoholer. Det er også mulig direkte å omsette reaksjonsblandingen, hvori forbindelsen med formel I fremkommer med aminer. Da i en slik reaksjonsblanding dessuten det ved reaksjonen dannede alkylhalogenid er tilstede, er det eventuelt nødvendig å anvende tilsvarende overskudd av amin. The formed 1,1-bis-[thienyl-(3 and/or 2)]-co-halo-alkanol of formula I can be reacted directly without further purification with amines. This turnover can take place with or without dissolution or suspending agent. Suitable as inert solvents or suspension agents are, for example, the same agents used for the reaction of thienyl lithium with compound II, for example diisopropyl ether, toluene and the like. In addition, for example, other alkyl and dialkylbenzenes, dialkyl ethers, aliphatic ketones and aliphatic and cycloaliphatic alcohols can also be used. It is also possible to directly react the reaction mixture, in which the compound of formula I appears with amines. Since in such a reaction mixture the alkyl halide formed by the reaction is also present, it is possibly necessary to use a corresponding excess of amine.
