Efficient Synthesis of Arylsilanes by Cross-coupling of Aromatic Compounds with Hydrosilanes as Silicon Sources

Hydrosilanes are compounds with active Si-H bonds and can be used as effective building blocks for synthesizing organic silicon-containing materials through metal-catalyzed hydrosilylation of olefinic substrates. Recently, novel transition metal-catalyzed cross-coupling reactions of aryl and heteroaryl compounds with hydrosilanes have been reported. These reactions proceeded efficiently under mild conditions, and in most cases arylated products were obtained in good to high yields with good functional group tolerance. This review presents the recent results of these research activities with respect to effective catalytic methods for the preparation of arylsilanes using hydrosilanes as silicon sources.
