(EN) PREPARATION OF ALKYL (AMINO) DIALKOXYSILANES
(FR) PREPARATION D'ALKYL (AMINO) DIALCOXYSILANES
Abstract
(EN)
Alkyl (amino) dialkoxysilanes are prepared by anhydrously reacting stoichiometric amounts of an alkoxysilane and an alkylaminomagnesium chloride in a reverse addition process. The alkylamino magnesium chloride is preferably prepared $i(in situ) by the reaction of a Grignard reagent (RMX) and an alkylamine in a suitable aprotic solvent, such as tetrahydrofuran. The 'alkyl' substituent can be alkyl, arylalkyl or aryl. The reaction can be conducted in the temperature range of from 25 °C to 75 °C, without a catalyst, and the aprotic solvent is recovered for re-use in the process.

L'invention concerne des alkyl (amino) dialkoxysilanes obtenus par la réaction anhydre de quantités stoechiométriques d'un alcoxysilane et d'un chlorure d'alkylaminomagnésium dans un procédé par addition inverse. Le chlorure d'alkylaminomagnésium est obtenu de préférence $i(in situ) par la réaction d'un réactif Grignard (RMX) et d'une alkylamine dans un solvant aprotique adéquat, notamment un tétrahydofurane. Le substituant 'alkyle' peut être alkyle, arylalkyle ou aryle. La réaction peut être menée à bien dans une plage de température comprise entre 25 et 75 °C, sans catalyseur et dans des conditions dans lesquelles le solvant aprotique est recouvert en vue d'une réutilisation dans le procédé.
