Efficient synthesis of vinyl and alkyl sulfides via hydrothiolation of alkynes and electron-deficient olefins using soluble and heterogenized gold complexes catalysts

Soluble and heterogenized gold complexes catalyze the hydrothiolation of alkynes and electron-deficient olefins in high yields and with high anti-Markovnikov selectivity. Moreover heterogenized catalysts could be recycled in several successive runs without any loss of activity or selectivity.
