The air-stable carbocation salt [(MeOC6H4)CPh2][BF4] in Lewis acid catalyzed hydrothiolation of alkenes†
Abstract
Markovnikov hydrothiolation of 1,1-disubstituted and trisubstituted olefins (20 examples) is catalyzed by Lewis acids, including the air-stable trityl-cation salt [(MeOC6H4)CPh2][BF4] 3.
