Definitions
- the invention relates to an organomagnesium synthesis agent, a process for the preparation of this synthesis agent and its use.
- An organomagnesium synthesis agent is used for the synthesis, in particular for organic synthesis.
- the present invention relates to organomagnesium compounds in highly concentrated solution.
- Organomagnesium compounds are known from the literature. Such compounds are synthesized, for example, by reacting mercury organyls with magnesium or by reacting aryl and alkyl halides with metallic magnesium. It is often necessary to use highly activated magnesium for synthesis, which is obtained, for example, by reduction of magnesium chloride by potassium (Ch Elschenbroich, A. Salzer, (1993), Organometallic Chemistry, 6.1 Alkaline earth metal organyls, 3rd edition, 1st corrected reprint, Teubner Economicsbücher Chemistry, Stuttgart).
- transition metal catalysts complexes of Cu, Fe, Ni, Pd and Pt salts
- other salts such as ZnCl 2 or ZnBr 2 are also frequently added in amounts up to stoichiometric (LS Hegedus, Organic Synthesis with Transition Metals, translated, processed and updated by H.-G. Schmalz and Andre Majdalani, (1995), VCH, Weinheim, page 81 ff):
- Organomagnesium compounds are also used in the synthesis of special boron compounds.
- boric acid esters such as trimethyl, triethyl or triisopropyl borate
- organomagnesium compounds alkyl or arylboranes, alkyl- or arylboronic acid esters or alkyl- or arylborinic acid esters are obtained.
- the two last-mentioned groups of substances form, after hydrolysis with water, alkyl- or arylboronic acids or alkyl- or arylborinic acids (R. Köster, Annalen der Chemie 1958, 618, 31, Synthesis and Use: DG Hall, (2005), Boronic Acids , Wiley-VCH Verlag, Weinheim).
- organomagnesium compounds in hydrocarbons, possibly with the addition of amines, or in solvents containing oxygen donors.
- a preferred laboratory-scale oxygen donor-containing solvent is diethyl ether. It is known from diethyl ether that organomagnesium compounds have a very high solubility therein and undesirable side reactions such as the coupling of aryl and alkyl halides with the organomagnesium compound (Wurtz coupling) occur only to a small extent (K. N Reifenel, (1973), Organomagnesium - A -
- organomagnesium compounds For the synthesis of organomagnesium compounds on an industrial scale, other oxygen donor-containing solvents such as, for example, tetrahydrofuran (THF), methyl tert-butyl ether (MTBE), diethoxymethane (DEM), dimethoxyethane (DME) or dioxane are initially suitable.
- THF tetrahydrofuran
- MTBE methyl tert-butyl ether
- DEM diethoxymethane
- DME dimethoxyethane
- dioxane dioxane
- the solubility of the organomagnesium compound can be partially increased in these solvents by admixing aromatic solvents such as benzene, toluene, xylenes, etc. (K. N Reifenel, (1973), Organomagnesium Compounds, in Eugen Müller, Houben Weyl, Volume 13 / 2a, fourth edition, Georg Thieme Verlag, Stuttgart).
- the object of the present invention is therefore to provide an organomagnesium synthesis agent which overcomes the disadvantages of the prior art.
- this synthesis agent should contain at least one organomagnesium compound in high concentration.
- the solvent used in the synthesis agent should have poor miscibility with water, and be used safely on an industrial scale.
- the preparation of the organomagnesium compound in this solvent should be possible, with no or only very minor side reactions during the production of organomagnesium compounds should occur.
- an organomagnesium synthesis agent containing in addition to at least one organomagnesium compound, a solvent containing at least one oxygen donor compound of the general formula 1 or consists of at least one oxygen donor compound of the general formula 1.
- the solvent according to the invention dissolves very well other organomagnesium compounds than propen-3-yl and benzyl compounds, that this inventive solvent is poorly miscible with water and enables safe use.
- DE-C-19808570 discloses that this shift in Schlenk equilibrium occurs.
- the solvent according to the invention is characterized by a high boiling point compared with diethyl ether. The risk of the formation of an explosive atmosphere is thus reduced on an industrial scale. For example, tetrahydro-2-methylfuran has a boiling point of 77-79X.
- the synthesis agent according to the invention is prepared by reacting at least one compound of the general formula R-X with magnesium in the solvent according to the invention of formula 2 or 3, thereby obtaining the desired organomagnesium compounds in the solvent according to the invention:
- R-MgX and R-Mg-R are organomagnesium compounds, where R-X, R-MgX and R-Mg-R are:
- R is selected from: functionalized and / or unfunctionalized branched and / or unbranched C 1 -C 20 -alkyl groups, C 1 -C 20 -haloalkyl groups with fluorine and / or chlorine as
- Halogen atom Ci-C 2 o-Alkoxy phenomenon, Ci-C 2 o-Halogenalk- oxy discipline with fluorine and / or chlorine as halogen atom, C 2 - C 2 o-Alkenyl phenomenon, C 2 -C 2 o-Alkinyl phenomenon, C 3 -C 8- C 1 -C 10 -alkyl groups and / or functionalized and / or unfunctionalized phenyl, phenoxy, aryl and / or hetaryl groups having 3 to 12 C atoms, which in turn may carry one or more of the abovementioned substituents R; and
- X is selected from: F and / or Cl and / or Br and / or I and / or triflate and / or tosylate, preferably from Cl and / or Br.
- R are: methyl, trimethylsilylmethyl, ethyl, ethenyl, ethynyl, trimethylsilylethynyl, dimethylthexylsilylethynyl, dimethylcyclohexylsilylethynyl, dimethyltertbutylsilylethynyl, triterbutylsilylethynyl, n-propyl, isopropyl, cyclopropyl, propyn-3-yl, n-butyl, cyclobutyl, 1-butene 4-yl, 1-but-4-yl, 2-buten-4-yl, crotyl, 2-butyn-4-yl, 2-butyl, iso-butyl, tert -

- the solvents according to the invention thus represent an ideal and safe diethyl ether surrogate for the preparation of other organomagnesium compounds than propen-3-yl or benzylmagnesium compounds.
