Borohydride catalyzed redistribution reaction of hydrosilane and chlorosilane: A potential system for facile preparation of hydrochlorosilanes

Various borohydrides were found to catalyze the redistribution reaction of hydrosilane and chlorosilane in different solvents to produce hydrochlorosilanes efficiently and facilely. The redistribution reaction was affected by solvent and catalyst. The substrate scope was investigated in HMPA with LiBH4 as catalyst. A possible mechanism was proposed to explain the redistribution process.

METHOD FOR PRODUCING -HETERO-SUBSTITUTED ALKYLHALOHYDROSILANE AND USE THEREOF

Method for efficiently producing α-hetero-substituted alkylhalohydrosilane,and use thereof. A method for producing (A) a halohydrosilane compound represented by the general formula (1): H-SiR2c(CR13-bYb)aX3-a-c (1) (wherein, R1 represents a hydrogen atom or a substituted or unsubstituted hydrocarbon group; R2 represents a substituted or unsubstituted hydrocarbon group; X represents a halogen atom; Y represents a hetero substituent; a is 1 or 2; b is any one of 1, 2 and 3; c is 1 or 0), by allowing (B) a halosilane compound represented by the general formula (2) : SiR2c(CR13-bYb)aX4-a-c (2) (wherein, R1, R2, X, Y, a, b and c are as defined above) to react with (C) a hydrosilane compound. A method for producing a reactive silicon group-containing polymer using the halohydrosilane compound (A).
