Abstract:
A process for preparing an organosilicon compound represented by formula I comprising: reacting a hydrochlorosilane represented by formula II with an organic halide represented by formula III in the presence of a Lewis base as a catalyst by a dehydrohalogenative coupling reaction;R.sup.3 CH.sub.2 SiR.sup.1 Cl.sub.2 (I)HSiR.sup.1 Cl.sub.2 (II)R.sub.2 CH.sub.2 X (III)wherein in formulas I and II, R.sub.1 represents a hydrogen, chloro, or methyl; in formula III, X represents a chloro or bromo; in formula III, R.sub.2 is selected from the group consisting of a C.sub.1-17 alkyl, a C.sub.1-10 fluorinated alkyl with partial or full fluorination, a C.sub.1-5 alkenyl group, a silyl group silyl group containing alkyls (CH.sub.2).sub.n SiME.sub.3-m Cl.sub.m wherein n is 0 to 2 and m is 0 to 3, aromatic groups, Ar(R').sub.1 wherein Ar is C.sub.6-14 aromatic hydrocarbon, R' is a C.sub.1-4 alkyl, halogen, alkoxy, or vinyl, and q is 0 to 5, a haloalkyl group, (CH.sub.2).sub.p X wherein p is 1 to 9 and X is a chloro or bromo, an aromatic hydrocarbon, and ArCH.sub.2 X wherein Ar is C.sub.6-14 aromatic hydrocarbon and X is a chloro or bromo and further wherein in formula I, R.sup.3 is the same as R.sup.2 in formula III and further, R.sup.3 can also be (CH.sub.2).sub.p SiR.sup.1 Cl.sub.2 when R.sup.2 in formula III is (CH.sub.2).sub.p X or ArCH.sub.2 X.
