摘要：

The reaction of the vinylidene(hydrido)ruthenium(ll) compound [RuHCl(=C=CH2)(PCy3)(2)] (1a) with excess KPF6 in CH2Cl2/CH3CN affords the five-coordinate vinyl comp lex [Ru(CH=CH2)(CH3CN)(2)(PCy3)(2)]PF6 (2a), which on treatment with NaBPh4 or NaB(Ar-f)(4) gives the tetraaryloborate salts 2b and 2c in excellent yields. The six-coordinate compounds [Ru(CH=CHPh)(CH3CN)(3)(PiPr(3))(2)]X (3a, X = Cl; 3b, X = PF6] were obtained in. a similar route using [RuHCl(=C=CHPh)(PiPr3)(2)] (1b) as the starting material. Protonation of 2c or 2d [X = BF4) with, respectively, [H(OEt2)(2)]B(Arf))4 or HBF4 yields [Ru(=CHCH3)(CH3CN)(2)(PCy3)(2)]X-2 (4a,b), which to the best of our knowledge represent the first dicationic carbeneruthenium(II) complexes.
