Abstract: The invention relates to a process for the manufacture of organomonosilanes, in particular, bearing both hydrogen and chlorine substituents at the silicon atom by subjecting a silane substrate comprising one or more organomonosilanes, with the proviso that at least one of these silanes has at least one chlorine substituent at the silicon atom, to the reaction with one or more metal hydrides selected from the group of an alkali metal hydride and an alkaline earth metal hydride in the presence of one or more compounds (C) acting as a redistribution catalyst.

Abstract: The invention relates to a process for the manufacture of organomonosilanes bearing both hydrogen and chlorine substituents at the silicon atom by subjecting a silane substrate comprising one or more silanes selected from organomonosilanes, organodisilanes and organocarbodisilanes, with the proviso that at least one of these silanes has at least one chlorine substituent at the silicon atom, to a redistribution reaction in the presence of a phosphane or amine acting as a redistribution catalyst.

Abstract: The invention relates to a process for the stepwise synthesis of silahydrocarbons bearing up to four different organyl substituents at the silicon atom, wherein the process includes at least one step a) of producing a bifunctional hydridochlorosilane by a redistribution reaction, selective chlorination of hydridosilanes with an ether/HCl reagent, or by selective chlorination of hydridosilanes with SiCl4, at least one step b) of submitting a bifunctional hydridochloromonosilane to a hydrosilylation reaction, at least one step c) of hydrogenation of a chloromonosilane, and a step d) in which a silahydrocarbon compound is obtained in a hydrosilylation reaction.
