- Trichlorosilyl groups containing organochlorosilanes and their preparation methods by the double-silylation of olefins with trichlorosilane
-
The present invention provides organosilicon compounds containing two trichlorosilyl groups and their preparation methods. Organosilicon compounds of formula II are prepared by reacting linear chain or cyclic olefins of formula I with trichlorosilane in the presence of quaternary organophosphonium salt as a catalyst.R1—HC=CH—R2??(I) 1In formulas I and II, R1 and R2 may be identical or different and represent a hydrogen atom, a linear or a cyclic C1-C8 alkyl, a linear or a cyclic C1-C8 alkenyl, benzyl, phenyl, a C1-C8 alkyl substituted phenyl group, two functional groups between R1 and R2 may be covalently bonded to form a C4-C8 ring with or without a carbon-carbon double bond.
