Title: Dehydrohalogenative coupling reaction of organic halides with silanes

Abstract: The present invention relates to methods for making the compounds of formula I which is a dehydrohalogenative coupling of hydrochlorosilanes of formula II with organic halides of formula III in the presence of a Lewis base catalyst. In formulas I and II, R.sup.1 represents a hydrogen, chloro, or methyl; in formula III, X represents a chloro or bromo; in formula III, R.sup.2 can be 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 groups, a 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; or an aromatic hydrocarbon, Ar CH.sub.2 X wherein Ar is C.sub.6-14 aromatic hydrocarbon and X is a chloro or bromo. 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 or ArCH.sub.2 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, because of the coupling reaction of X with the compound of formula II.
