  名称：

  Reaction of the dinuclear cobalt complex [Co2{μ-PPh2CHCHC(O)CHCHPPh2}(CO)4] with two-electron donor ligands; the stabilisation of cobalt-alkene bonds by incorporation of alkenes into a bridging diphosphine ligand

  摘要：

  The thermal reaction of [Co-2{mu-PPh2CHCHC (O) CHCHPPh2} (CO)(4)] (2) with two-electron donor ligands, L, leads to the mono- and bis-substituted complexes [Co{mu-PPh2CHCHC (O) CHCHPPh2} (CO)(3)(L)] (L = PPhMe2 (3a), PPh2H (3b), P(OMe)(3) (3c), (CNBu)-Bu-t (3d)) and [Co-2{mu-PPh2CHCHC (O) CHCHPPh2} (CO)(2)(L)(2)] (L = PPhMe2 (4a), PPh2H (4b), P(OMe)(3) (4c), (CNBu)-Bu-t (4d)), in which CO groups rather than bound alkenes have been displaced from the metal centres. Single crystal X-ray diffraction has: been used to determine the structure of [Co-2{mu-PPh2CHCHC (O) CHCHPPh2} (CO)(2) (PPhMe2)(2)]. 0.25[C6H14] (4a) (which crystallises in the monoclinic space group P2(1)/c with a = 15.932(2), b = 12.608(4), c = 23,847(3) Angstrom, beta = 98.87(3)degrees, Z = 4).
