Polarity-reversal catalysis by thiols of radical-chain hydrosilylation of alkenes
摘要:
The radical-chain hydrosilylation of alkenes by triethylsilane under very mild conditions is promoted by thiols, which act as polnrity-reversal catalysts for the abstraction of electron-rich hydrogen from the silane by nucleophilic beta-silylalkyl radicals.
