The transition metal-catalyzed hydrosilylation reaction of C-H bond activation is of great significance in the fields of materials science and synthetic chem. Organosilicon compounds are widely used in textile, rubber, machinery, daily chem. and other materials. In addition, they are also important organic synthesis intermediates. As nucleophile, they are applied to Hiyama coupling reaction, and the reaction has the characteristics of economy, high efficiency and environment friendly. In recent years, many research groups have carried out studies in this field and achieved certain results. This article will mainly introduce the research progress in transition metal-catalyzed hydrosilylation reaction of aryl/alkyl C-H bond activation in recent years.
