  摘要：

  Substituted salicylaldehydes [(C6HRRR3)-R-1-R-2(CHO)(OH)] react with CoMe3(PMe3)(3) to afford 6-coordinate (cis-dimethyl)(2-formyl-phenolato)trans-bis(trimethylphosphine)cobalt(III) compounds CO[(C6HRRR3)-R-1-R-2 (CHO)(O)Me-2](PMe3)(2) (1: R-1 = H; R-2 = Me; R-3 = tert-Bu; 2: R-1, R-2 = C6H4; R-3 = H). Accordingly, substituted enolated malonic dialdehydes (CHO-CR4 = CR5-OH) react with CoMe3(PMe3)(3) to afford 6-coordinate (cis-dimethyl)(2-formyl-enolato)trans-bis(trimethylphosphine)cobalt(III) compounds Co((CHO-CR4=CR5-O)(Me)(2)](PMe3)(2) (3: R-4, R-5 = (CH2)(2)C6H4; 4: R-4 = R-5 = C6H5). In the molecular structure of 4, the cobalt atom is centred in an octahedral coordination geometry brought about by a six-membered chelate ring (O:O-ligand), cis-dimethyl and trans-trimethylphosphine groups. A reaction mechanism is suggested. (c) 2005 Elsevier B.V. All rights reserved.
