    Abstract: The silahydrocarbon product containing at least 75 weight percent of saturated silahydrocarbons with the remainder being unsaturated silahydrocarbons is produced by a process in which admixture comprising(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 having the formulaR--SiH.sub.2 --R.sub.1(ii) a trialkylsilane having the formula ##STR1## and (iii) mixtures thereof,wherein R and R.sub.1, the same or different, each represent an alkyl radical of from one to 20 carbon atoms per molecule with a catalyst comprising a homogeneous rhodium-containing catalyst or a heterogeneous rhodium-containing catalyst in a halogen-free inert solvent, under hydrosilylation reaction conditions to produce a mixture containing saturated and unsaturated silane hydrocarbons useful as lubricants. The unsaturated silane hydrocarbons can be substituted with sulfur to provide improved lubricating characteristics.
