  摘要：

  Reactions of [(eta(6)-1 2,4,5-Me40C6H2)Ru(DPVP)Cl-2] (DPVP = diphenylvinyl phosphine), with (trimethylsilyl)acetylene and phenylacetylene in the presence of NaPF6 in methanol gave the (methoxy)-alkylcarbene complexes [(eta(6)-1,2,4,5-Me4C6H2)Ru(=C (OMe)(R))(DPVP)(Cl)]PF6 (R = CH3, 1a; CH2Ph, 2a). Similarly, treatment of [(eta(6)-1 2,4-Me3C6H2-5-CH2CH2CH2P(C6H5)(2))RuCl2] with (trimethylsilyl) acetylene, phenylacetylene and 1,1-diphenylpropargyl alcohol in the presence of NaPF6 gave the tethered carbene complexes [(eta(6)-1 2,4-Me3C6H2-5-CH2CH2CH2P(C6H5)(2))Ru(=C(OMe)(R))(Cl)PF6 (R = CH3, 1b; CH2Ph, 2b; CH=C-Ph-2, 3b), respectively. The complexes, [(eta(6)-arene)Ru(DPVP)Cl-2] and [(eta(6)-arene-CH2CH2CH2P(C6H5)(2))RuCl2] are shown to be useful catalyst precursors for the hydration of phenylacetylene to afford acetophenone. The complexes, [(eta(6)-arene)Ru(DPVP)Cl-2] (arene = 1,3,5-Me3C6H3 1, p -MeC6H4CHMe2 2, 1,2,4,5-Me4C6H2 3 and Me6C6 4) react with excess phenyl-isocyanide and NaPF6 in methanol to produce [(eta(6)-arene)Ru(DPVP)(CNPh)(Cl)]PF6 derivatives 1c-4c. The related tethered complexes Id and 2d were prepared from [(eta(6)-arene-CH2CH2CH2P(C6H5)(2))RuCl2] by using the same methodology. All the complexes have been characterized spectroscopically and the crystal structures of some of them have been obtained. (C) 2002 Elsevier Science B.V. All rights reserved.
