Abstract

Summary Observations on olefin/SiH4 reactions (olefin isomerization, alkylsilane formation) are consistent with Barton mechanisms involving silacyclopropane and alkylsilylene intermediates. SCP ring-forming and-opening reactions are at least an order of magnitude faster than their decompositions (to olefins and SiH2). All reactions are pressure dependent at 400 Torr. On the basis of butylsilylene-and pentylsilylene-trapping reactions with silane ...
