A highly regioselectivehydrosilylation of propargylicalcohols has been developed using an in situ prepared PtCl(2)/XPhos catalyst system. The reaction is tolerant of many functional groups and exhibits excellent regio and geometric selectivity.

A facile and user-friendly protocol has been developed for the selective synthesis of E-vinyl silanes derived from propargylicalcohols using a PtCl2/XPhos catalyst system. The reaction is generally high yielding and provides a single regioisomer at the β-position with E-alkene geometry. The reaction is extremely tolerant of functionality and has a wide scope of reactivity both in terms of alkynes
