Highlyregio- and stereoselective hydrothiolation of a wide range of alkynes with various thiols was demonstrated in the presence of a well-defined Rh complex supported on mesoporous SBA-15 silica. The catalyst was easily recovered and reused several times without significant loss of activity or selectivity.
Received mm-dd-yyyy Accepted mm-dd-yyyy Published on line mm-dd-yyyy Dates to be inserted by editorial office Abstract α-Heterosubstituted silyl derivatives, such as phenylthio-, phenylselenoand benzotriazolyl-stannyl silanes, react with aldehydes under TBAF catalysis, leading to α-substituted-β-hydroxy stannanes, able to behave as precursors of Zand E-olefins, generated by deoxystannylation.

A new copper and iodine-mediated C–H oxidative sulfenylation of olefins with diaryl disulfides for the stereospecific synthesis of vinyl thioether is described.
