  摘要：

  A series of five (C:O)-dianionic 1-acyl-2-enolato ligands C(O)-C=C-O in a transmetallation reaction between 18-electron metal-d(6) complexes mer-trans-NiMe(X)[C(O)-C=C-O](PMe3)(2) [C=C=C6H4, X = I (1); C=C=3-CMe3-5-Me-C6H2, X=I (2); C=C=5,6-benzo-C6H2, X = I (3); C=C=3,4-benzo-cyclohexene, X = Br (4); C=C=1,2-diphenylethene, X = I (5)] and the 18-electron metal-d(8) compound CoMe(PMe3)(4) (1:2), undergo a reductive coupling of acyl and methylnickel functions involving the C(O)-C=C-O ligands. Subsequent migration of methyl groups between cobalt intermediates generates three products: mer-trans-CoMe2[MeC(O)-C=C-O](PMe3)(2) (6-10), Ni(PMe3)(4), and CoX(PMe3)(3). The X-ray crystal structure of compound 7 has been determined. The methyl ligands are found in positions opposite to the O-donor functions. Upon replacing the aromatic rings in salicylaldehyde derivatives C(O)-C=C-O by more flexible cyclohexene rings or acyclic systems the reduction of Ni(IV) complexes follows a different course.
