Production of saturated and unsaturated silahydrocarbon mixtures using rhodium catalyst, and to products produced thereby
This patent describes a process for the production of a mixture of saturated and unstaurated silahydrocarbons. This process contacts an admixture consisting of (A) at least one alpha-olefin containing from 2 to about 20 carbon atoms per molecule, and (B) at least one alkylsilane selected from the group consisting of (i) a dialkylsilane (ii) a trialkylsilane (iii) mixtures thereof, with a catalyst consisting of a homogeneous monomeric rhodium-containing catalyst having a basicity substantially equal to or less than that provided by a rhodium-containing catalyst having a triphenyl phosphine ligand or a heterogeneous rhodium-containing catalyst in a halogen-free inert solvent. The process conducted at a temperature of from about 30/sup 0/ to about 200/sup 0/C., a weight ratio of olefin to alkylsilane of from about 0.5 to about 20 to one and a catalyst concentration of from about 1 x 10-/sup 5/ to about 1 x 10-/sup 2/ millimoles of catalyst per millimole alkylsilane, to produce a mixture containing saturated silane hydrocarbons and an unsaturated silahydrocarbon. Inclusive with the proviso that the molecular weight of the unsaturated silane hydrocarbon is above 300.
