di-alkenyl sulphides of the type RS(CH2)nCHCH2 (R = C2H5, CH2CH, CH2CHCH2, C3H7, n = 0, 1 and 4) by triethyl- and triethoxy-silane, catalyzed by H2PtCl6·6 H2O, (Ph3P)3RhCl and (PhCN)2PdCl2·Ph3P, has been studied. The addition of hydrosilane to the double bond of alkenyl sulphide leads to a mixture of two isomeric monoadducts. The hydrosilane can cleave the CS bond of the initial sulphides giving the
