    • 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. R3CH2SiR1Cl2  (I) HSiR1Cl2  (II) R2CH2X  (III) In formulas I and II, R1 represents a hydrogen, chloro, or methyl; in formula III, X represents a chloro or bromo; in formula III, R2 can be selected from the group consisting of a C1-17 alkyl, a C1-10 fluorinated alkyl with partial or full fluorination, a C1-5 alkenyl groups, a silyl group containing alkyls, (CH2)nSiMe3-mClm wherein n is 0 to 2 and m is 0 to 3, aromatic groups, Ar(R′)1 wherein Ar is C6-14 aromatic hydrocarbon, R′ is a C1-4 alkyl, halogen, alkoxy, or vinyl, and q is 0 to 5, a haloalkyl group, (CH2)pX wherein p is 1 to 9 and X is a chloro or bromo; or an aromatic hydrocarbon, Ar CH2X wherein Ar is C6-14 aromatic hydrocarbon and X is a chloro or bromo. in formula I, R3 is the same as R2 in formula III and further, R3 can also be (CH2)pSiR1Cl2 or ArCH2SiR1Cl2 when R2 in formula III is (CH2)pX or ArCH2X, because of the coupling reaction of X with the compound of formula II.
