Abstract

Abstract : Sodium triethylborohydride has been found to be a highly selective catalyst for the dehydrogenative silylation of aromatic and aliphatic alkynes with hydrosilanes. Abstract : The first example of sodium triethylborohydride-catalyzed C(sp)–H bond silylation is reported. The reaction of aromatic and aliphatic alkynes with aromatic hydrosilanes and hydrosiloxanes proceeded in a highly selective manner to afford dehydrocoupling products. Competitive hydrosilylation of the terminal alkyne did not occur as a side-reaction. In view of the above it is remarkable that NaHBEt3 is commonly used as a reducing agent generating active transition-metal catalysts in situ in other hydrosilylation reactions.
