Abstract

Hydrosilanes are unique compounds with active Si-H bonds. Hydrosilanes can be used as effective building blocks for synthesizing organic/inorganic silicon-containing materials. In this account the catalytic coupling of hydrosilanes with molecules having active E-H bonds (E = Si, O, N) or vinylic bonds via Si-Si/Si-O/Si-N dehydrocoupling, Si-C redistributive coupling, and hydrosilation to useful silicon-containing materials is described. This account presents selective examples of our recent research developments in silicon materials chemistry along with the inspiration and rationale for promoting the synthetic chemistry of hydrosilanes via catalysis.
