Abstract

Abstract: The disproportionation of(C₂H₅O)₃SiH and CH₃SiH(OC₂H₅)₂using DMF or THF as the solvents in the presence of KF(and 18-crown-6)was studied and the effects of catalyst system,temperature and solvent on the disproportionation were discussed. The results showed that KF/18-crown-6 is a good catalytic system for the disproportionation of hydroalkoxysilones, the solvent and temperature affect obviously the reaction.

Key words: Disproportionation, Fluorides, Catalysis, Alkoxysilanes
