IPC: B01J31/12
Filed: 1991-05-31
Abstract: PURPOSE:To convert an alkylhydrosilane into an alkylhydrosilane or alkylsilane incorporated with one more alkyl group in one step using an inexpensive catalyst. CONSTITUTION:An alkylhydrosilane or an alkylsilane incorporated with one more alkyl group is produced from an alkylhydrosilane in one step without using an ether-type solvent by reacting an alkylhydrosilane with an unsaturated hydrocarbon such as 1-hexene in the presence of an inexpensive metal hydride catalyst such as LiAlH4.
