Description
Foreliggende oppfinnesle vedrører en fremgangsmåte for syn-tese av karbonylforbindelser inneholdende en eller flere funksjonelle grupper utover karbonylgruppen i deres struktur. The present invention relates to a method for the synthesis of carbonyl compounds containing one or more functional groups in addition to the carbonyl group in their structure.
Fremgangsmåten i henhold til oppfinnelsen består i at en karbonylforbindélse omsettes med en forbindelse inneholdene ic.det:^minste en umettetrbinding :(dobbeltbinding eller trippel-binding) og en eller flere funksjonelle grupper, idet reaksjonen gjennomføres i nærvær av katalytiske mengder peroksyder. The method according to the invention consists in reacting a carbonyl compound with a compound containing at least one unsaturated bond (double bond or triple bond) and one or more functional groups, the reaction being carried out in the presence of catalytic amounts of peroxides.
Karbonylforbindelsen kan være et alifatisk, aromatisk eller alisykliske keton eller aldehyd, med en metyl- eller metylengruppe CÅ -stillingen i forhold til karbonylgruppen, og kan spesielt være et <X -metylketon. The carbonyl compound may be an aliphatic, aromatic or alicyclic ketone or aldehyde, with a methyl or methylene group in the CÅ position relative to the carbonyl group, and may in particular be a <X methyl ketone.
Den umettede forbindelse kan som nevnt inneholde én ellerAs mentioned, the unsaturated compound may contain one or
flere olefinbindinger og/eller en eller flere acetylenbind-inger, idet en umettet binding i en endestilling foretrekkes, og kan også innehold én eller flere funksjonelle grupper som kan velges f. eks. fra-OH, -OOCCH3, -Cl, -OCH3, -OC2Hj- , -CN, several olefin bonds and/or one or more acetylene bonds, with an unsaturated bond in an end position being preferred, and may also contain one or more functional groups which can be chosen, e.g. from-OH, -OOCCH3, -Cl, -OCH3, -OC2Hj- , -CN,
-COOH, -COOR.-COOH, -COOR.
Radikal-addisjonsreaksjonen av ketoner til :ok -olefiner eller cykloheksen har vært kjent i noen tid og fremmes f.eks. ved overgangsmétallsalter eller oksyder. I dette tilfellet oppnås lave utbytter av brukbart sluttprodukt. Organiske peroksyder eller; peroksyéstere som radikalkilder har også vært anvendt i støkiométriske mengder i forhold til den initiale karbonylforbindélse. ILtillegg til å oppnå sluttprodukter med abso-lutt utilfredstillende omdannelse og selektivitet, pluss nærvær av en uforholdsmessig stor mengde av peroksyd, er det aldri tidligere nevnt muligheten av å fremstille forbindelser inneholdende svært forskjellige funksjonelle grupper, slik at muligheten av gjennomføringen av reaksjonen direkte mellom karbonylforbindelsen og den umettede forbindelse inneholdende en eller flere funksjonelle grupper ikke var påtenkt. The radical addition reaction of ketones to :ok -olefins or cyclohexene has been known for some time and is promoted e.g. by transition metal salts or oxides. In this case, low yields of usable final product are obtained. Organic peroxides or; peroxyesters as radical sources have also been used in stoichiometric amounts in relation to the initial carbonyl compound. In addition to obtaining final products with absolutely unsatisfactory conversion and selectivity, plus the presence of a disproportionately large amount of peroxide, the possibility of preparing compounds containing very different functional groups, so that the possibility of carrying out the reaction directly between the carbonyl compound, has never before been mentioned and the unsaturated compound containing one or more functional groups was not contemplated.
Den erkjennelse som ligger til grunn for den foreliggende oppfinnelse er at det er funnet mulig å reagere en karbonylforbindelse med en forbindelse inneholdende i det minste en umettet binding samtidig med en eller flere funksjonelle grupper i nærvær av bare katalytiske peroksydmengder. På denne måte oppnås høy omdannelse og selektivitet til brukbare sluttprodukter idet de sistnevnte også omfatter forbindelser inneholdende karbonylgruppen samtid med en eller flere funksjonelle grupper hvor nærværet av disse aldri var; postulert eller påtenkt sammen med karbonylgruppen. Disse inkluderer eterne og esterne av 6-metylheptan-6 -ol-2-én .... Reaksjonen gjennomføres derfor i nærvær 'av et peroksyd i en mengde slik at dets molforhold til den umettede forbindelse varierer fra 1/1 til 0,005/1. Peroksyder anvendbare for dette formål er diacetylperoksyd, dibenzoylperoksyd, tért-butylhydroperoksyd, dicykloheksylperoksydekarbonat, etc. idet bruken av d-tert-butylperoksyd har vist seg spesielt fordelaktig.. Reaksjonen kan gjennomføres ved å gå ut fra substratene alene, eller alene, eller kan gjennomføres i nærvær av vann i en slik mengde at det utgjør enten en enkelLvæskefase eller to væske-faser med blandingen av den umettede "forbindelse og karbonylforbindelsen som bringes til reaksjon. The recognition that underlies the present invention is that it has been found possible to react a carbonyl compound with a compound containing at least one unsaturated bond simultaneously with one or more functional groups in the presence of only catalytic amounts of peroxide. In this way, high conversion and selectivity to usable end products is achieved, as the latter also include compounds containing the carbonyl group together with one or more functional groups where the presence of these was never; postulated or contemplated together with the carbonyl group. These include the ethers and esters of 6-methylheptan-6-ol-2-ene.... The reaction is therefore carried out in the presence of a peroxide in an amount such that its molar ratio to the unsaturated compound varies from 1/1 to 0.005/1 . Peroxides useful for this purpose are diacetyl peroxide, dibenzoyl peroxide, tert-butyl hydroperoxide, dicyclohexylperoxydecarbonate, etc., the use of d-tert-butyl peroxide having proved particularly advantageous.. The reaction can be carried out by starting from the substrates alone, or alone, or can be carried out in the presence of water in such an amount as to form either a single liquid phase or two liquid phases with the mixture of the unsaturated compound and the carbonyl compound being reacted.
Tilførselen av disse er slik at molforholdet mellom karbonylforbindélse og umettet forbindelse varierer fra 500/1 til 3/1, og spesielt fra 300/1 til 5/1. Det bemerkes til slutt at de forbindelser som oppnås ved fremgangsmåten i henhold til j oppfinnelsen har forskjellige anvendelser. F.eks. kan det produkt som oppnås ved å gå ut fra aceton og 2-metyl-3-buten-2-ol, nemlig 6-metylheptan-6-ol-2-6n , utgjøre utgangsforbindélse for fremstilling av tallrike terpen dérivater som f.eks. hydroksylinanol, citral, hydroksycitral, hydroksycitronellal, geranonitril, iononer etc. anvendt innenfor områdene aroma, parfyme, vitaminer, medisiner og overflateaktive forbindelser. The supply of these is such that the molar ratio between carbonyl compound and unsaturated compound varies from 500/1 to 3/1, and especially from 300/1 to 5/1. It is finally noted that the compounds obtained by the method according to the invention have different applications. E.g. can the product obtained by starting from acetone and 2-methyl-3-buten-2-ol, namely 6-methylheptan-6-ol-2-6n, constitute the starting compound for the production of numerous terpene derivatives such as e.g. hydroxylinanol, citral, hydroxycitral, hydroxycitronellal, geranonitrile, ionones etc. used in the areas of aroma, perfume, vitamins, medicines and surface-active compounds.
Derivater av det nevnte metylheptanolon, som har spesielt verdifulle luktegenskaper, kan oppnås fra aceton og etere eller estere av 2-metyl-3-buten-2-ol ved direkte foretring eller forestring av metyl-heptanolonet. De følgende eksempler illustrerer syntesene for fremstilling av de angjeldende forbindelser. Derivatives of the aforementioned methylheptanolone, which have particularly valuable odor properties, can be obtained from acetone and ethers or esters of 2-methyl-3-buten-2-ol by direct etherification or esterification of the methylheptanolone. The following examples illustrate the syntheses for the preparation of the compounds in question.
EKSEMPEL 1EXAMPLE 1

The mixture is then heated with stirring to 125°C and after 1;. hour and 45 minutes of reaction, the MBE conversion (initial moles of MBE minus final moles of MBE)x100/initial moles of MBE) is 66% and the selectivity with respect to the 4:1 addition product (moles of product x 100/mol of reacted MBRE) is 86%.
Etter 5 timer er omdannelsen 98% og selektiviteten er omtrent 82%. After 5 hours the conversion is 98% and the selectivity is about 82%.
