- Silahydrocarbons from alkylchlorosilanes
-
A process for the production of tetra- and trialkylsilanes which comprises reacting (A) an alkylchlorosilane having the formula wherein R is an alkyl radical containing from one to three carbon atoms per molecule and x is an integer from 0 to 3, with (B) a trialkylaluminum compound having the formula STR1 wherein R1, R2 and R3 are the same or different and represent alkyl radicals containing from 6 to 20 carbon atoms per molecule, in a reaction zone, said reaction being conducted under hydrosilylation conditions. Selectivity to tetra- or trialkylsilanes, respectively, is controlled by the addition of particular alkaline metal salts to the reaction zone.
