摘要：

Reactions of Ru(C=CC6H4C=CR-4)(PPh3)(2)Cp [R = SiMe3 (1), H (3)] are described. With Co-2(CO)(8) reactions occur at the C=C triple bond furthest from the ruthenium centre; in contrast, tetracyanoethene gave Ru{eta(3)-C[=C(CN)(2)]C(C6H4C=CR-4)=C(CN)(2)}(PPh3)Cp (R = SiMe3, H), the molecular structure of the latter being determined. Protonation or methylation of 3 occurs at Cg to give the expected vinylidene complexes. With 3, metallation (LiBu), Sonogashira and oxidative coupling reactions were demonstrated. Coupling with appropriate metal substrates gave a variety of complexes containing RuC=CC6H4C=CM (M = W, Rh, Ir, Pt, Au, Hg) moieties. (C) 1999 Elsevier Science S.A. All rights reserved.
