  Preparation of [Ru(η⁶-C₆Me₆)Cl(CCPh)(RNC)](R = C₈H₉or C₆H₂Me₃-2,4,6) and its reaction with tetracyanoethylene. Crystal structures of [Ru(η⁶-C₆Me₆)Cl{C[C(CN)₂]CPhC(CN)₂}(C₈H₉NC)] and cis-[RuCl₂(C₈H₉NC)₂]

  摘要：

  Reaction of [Ru(eta(6)-C(6)Me(6))Cl-2(RNC)] with phenylacetylene in the presence of potassium hydroxide in methanol gave the corresponding acetylide complex [Ru(eta(6)-C(6)Me(6))Cl(C=CPh)(RNC)] (R = C8H9 1a or 2,4,6-Me(3)C(6)H(2) 1b). Compound la reacted with triphenylphosphine at reflux in toluene to give [RU(eta(6)-C(6)Me(6))Cl(C=CPh)(PPh(3))] 2 and [RUCl(C=CPh)(C8H9NC)(PPh(3))] 3. When 1a was treated with tetracyanoethylene (tcne) at room temperature [Ru(eta(6)-C(6)Me(6))Cl{C[=C(CN)(2)]CPh=C(CN)(2)}(C8H9NC)] 4 was obtained. The structure was confirmed by an X-ray analysis: space group Pbca, a = 20.128(4), b = 17.821(6), c = 17.407(9) Angstrom, and Z = 8. The molecule contains a ligand resulting from alpha,beta addition. of C(CN)(2) fragments to the acetylide group. Reaction of 2 with tcne gave [RU(eta(6)-C(6)Me(6))Cl{C(CN)(2)CPhC=C(CN)(2)}] 5 which has lost the terminal isocyanide in 4. Preparation and X-ray analysis of square-planar cis-[RuCl2(C8H9NC)(2)] were also carried out: space group P ($) over bar 1, a = 10.573(3), b = 10.865(3), c = 8.244(2) Angstrom, alpha = 99.66(2), beta = 93.37(2). gamma = 85.85(3)degrees and Z = 2. The structure consists of a pair of molcules of cis configuration with a centrosymmetry, but there is no interaction between the ruthenium atoms.
