The treatment of a variety of hydrosilanes, each incorporating a benzylic C(sp3)–H bond, with a rhodium catalyst resulted in intramolecular dehydrogenativesilylation. This silylation reaction was found to occur at typically unreactive C(sp3)–H bonds located at terminal positions on alkyl chains. Interestingly, the rhodium catalyst also promoted regioselective silylation at a site internal to an alkyl
