Alkenes and ketones are easily hydrosilylated by tris(trimethylsilyl)silane (1) via a radical mechanism, initiated by photolysis or a radical initiator. In the case of 1,6-dienes or 1-en-6-ones, the intermediate silylalkyl or siloxyalkyl radical, respectively, is trapped intramolecularly to give substituted cyclopentanes.
