, p. 771 - 774 (1984)
Infrared gas phase spectra in the SiH and GeH stretching regions are reported for cyclopropyl-SiH3, -SiHD2, GeHD2, cyclopentyl-SiHD2 and -GeHD2.In each case two bands are seen which indicate the presence of stronger MHa and weaker MHs/sub

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.

Novel silane compound, alkoxy cyclopentyl diethoxysilane, is prepared by reacting cyclopentyl trihalosilane with ROH and then with ethanol, or by reacting cyclopentyl triethoxysilane with ROH, wherein alkyl in the alkoxy or R in ROH stands for an organic group selected from tile group consisting of isopropyl, sec-butyl, tert-buryl and tert-amyl groups. The silane compounds are useful as a catalytic component for olefin polymerization and as a silane coupling agent.
