摘要：

The synthesis, structure, and reactivity properties of CpRu(dfepe)Cl (1, dfepe = (C2F5)2PCH2CH2P(C2F5)2) are reported. Thermolysis of CpRu(Ph3P)2Cl in hydrocarbon solvent with excess dfepe at 140-degrees-C gives 1 in good yield. In contrast to donor phosphine analogues, the chloride ligand in 1 is not labilized by halide-abstracting agents in the absence of trapping ligands. Crystallographic data for 1 confirm the presence of a short Ru-Cl bond (2.406 (1) angstrom). Sodium naphthylide reduction of 1 produces the thermally stable anion, Ne[CpRu(dfepe)]- which upon treatment with NH4+PF6- or CH3I affords the corresponding hydride and methyl derivatives CpRu(dfepe)H (3) and CpRu(dfepe)Me (4) in moderate yield. The hydride complex 3 is more conveniently prepared by the reaction of 1 with AgBF4 under 1 atm of H-2, presumably via the incipient formation of a highly acidic dihydrogen or dihydride cationic complex. Crystal data for 1: monoclinic, P2(1)/n, with a = 7.7709 (15) angstrom, b = 14.224 (2) angstrom, c = 20.814 (4) angstrom, beta = 91.670 (15)-degrees, V = 2299.6 (7) angstrom3, Z = 4, R(F) = 5.21%, and R(wF) = 7.21%.
