-
, (2008/06/13)
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, R1represents a hydrogen, chloro, or methyl; in formula III, X represents a chloro or bromo; in formula III, R2can be selected from the group consisting of a C1-17alkyl, a C1-10fluorinated alkyl with partial or full fluorination, a C1-5alkenyl groups, a silyl group containing alkyls, (CH2)nSiMe3-mClmwherein n is 0 to 2 and m is 0 to 3, aromatic groups, Ar(R′)1wherein Ar is C6-14aromatic hydrocarbon, R′ is a C1-4alkyl, 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 C6-14aromatic hydrocarbon and X is a chloro or bromo. in formula I, R3is the same as R2in formula III and further, R3can also be (CH2)pSiR1Cl2or ArCH2SiR1Cl2when R2in formula III is (CH2)pX or ArCH2X, because of the coupling reaction of X with the compound of formula II.

Allyltrichlorosilanes are prepared according to a one-step regiospecific process based on the reaction of allyl chlorides with SiCl4 and NiCp2/HMPA (catalyst), in the presence of industrial methylchlorodisilane fraction.Benzyltrihalosilanes are similarly obtained.
