Totally regioselective hydrosilylation of functionalized terminal arylalkynes was achieved using PtCl(2) associated with the air-stable and bulky Xphos ligand with various silanes. Regardless of the electronic nature of the substituents on the aromatic ring, a single beta-(E)-vinylsilane was obtained in excellent yields. (C) 2008 Elsevier Ltd. All rights reserved.
