摘要：

First generation Grubbs catalyst [RuCl2(PCy3)(2)(=CHPh)] and related complexes of a general formula [RuCl2(PCy3)(2)(=CHR)], where R is an aromatic or methyl group, undergo efficient reaction with trimethylsilylacetylene and related silylacetylenes to form vinyl carbene complexes [RuCl2(PCy3)(2)(=CHCH=CHR)] and disiloxane. The reaction requires the presence of water in the reaction medium. It is a convenient method for the high-yield synthesis of ruthenium vinyl carbene complexes. For benzylidene complexes, the reaction gives exclusively E-geometry of vinyl carbene ligand. (C) 2013 Elsevier B. V. All rights reserved.
