KINETICS AND MECHANISM OF THE PYROLYSIS OF ALLYLTRIMETHYLSILANE.

Article abstract of DOI:10.1021/ja00333a043

The gas-phase thermal decomposition of allyltrimethylsilane has been reinvestigated by using deuterium labeling and kinetic studies of variable pressure. Trimethylvinylsilane, the major product at high pressures, is found not to be a primary product of unimolecular decomposition. Silyl radical trapping allowed kinetic separation of the two competitive primary processes of decomposition: a concerted retroene elimination of propene to directly produce a silene and Si-C bond homolysis.
