Autoxidation of Tris(trimethylsilyl)silane

Tris(trimethylsilyl)silane reacts spontaneously at ambient temperature with molecular oxygen to form (Me3SiO)2Si(H)SiMe3 in high yield.The reaction proceeds via a free-radical chain mechanism and probably involves three consecutive unimolecular processes which are unknown in the literature.

Photolysis of tris(trimethylsilyl)silane: Trapping of sisyl radicals

The photolysis of tris(trimethylsilyl)silane (TTMSS) was studied in the absence and in the presence of added trapping agents such as alkenes and alcohols. It was found that, unlike the case with pyrolysis, silyl radicals rather than silylenes are produced
