Also, novel organosilicon compounds prepared by the present process is provided herein. The process comprises the reaction of a halosilane with an organofunctional alkyl halide in the presence of a metal catalyst, a promoter, and an optional co-catalyst. The process provides an efficient synthetic route to produce organosilicon compounds. The process also allows synthesis of organosilicon compounds with a plurality of different functional groups.

专利号:US-7709672-B2 优先权日:2001-09-21 标 题:Method for obtaining halogenated monoorganoxysilanes useful in particular as synthesis intermediates 发明人:GUENNOUNI NATHALIE; MIGNANI GERARD; PEVERE VIRGINIE 权利人:RHODIA CHIMIE SA 摘要:The invention concerns the preparation of halogenated monoorganoxysilanes, of formula (I), said compounds being useful as synthesis intermediate in organic chemistry. Said method for preparing monoorganoxysilanes consists in: using as starting product halogenoalkylsilanes of the (CH 3 ) 2 SiCl 2 type and in substituting the silicon with a radical bearing a divalent unit bound to an electrophilic reactive group capable of reacting with at least an appropriate nucleophilic agent to form a functionalised monoorganoxysilane of formula (II) with, for example: R<1>=C 1 -C 4 alkyl; R<2>, R<3>=C 1 -C 6 alkyl; B=C 1 -C 10 alkylene; m=1 or 2; Hal=halogen; W=amino, mercapto, (organosilyl)-organopolythio radical.
