  Synthesis and structures of aryl-substituted tetramethylcyclopentadienyl dinuclear metal carbonyl complexes

  摘要：

  A series of 14 aryl-substituted tetramethylcyclopentadienyl dinuclear metal carbonyl complexes have been synthesized by treating the corresponding ligands (C5Me4C6H4X-4) (X = H, Me, Cl, OMe) with Ru-3(CO)(12), Fe(CO)(5), or Mo(CO)(3)(MeCN)(3), respectively in refluxing xylene. It showed that the electronic effects of the substituents had influence on the molecular structures and reactions of the complexes, especially for the ruthenium and molybdenum complexes. In the reactions of aryl-substituted tetramethylcyclopentadiene with Mo(CO)(3)(MeCN)(3), the electron-withdrawing effect of the substituent in the para position of benzene ring is favorable to produce the Mo-Mo triple bonded complexes, but the electron-donor effect of the substituent in the para position of benzene ring is favorable to produce the Mo-Mo single bonded complexes. In a given condition, the Mo-Mo single bonded complex could be transformed into the corresponding Mo-Mo triple bonded complex. The structures of nine complexes were determined by single crystal X-ray diffraction. (c) 2006 Elsevier B.V. All rights reserved.

The efficiency of the transfer hydrogenation reactions was highly dependent on the nature of the chelating ligand and the Cpx ring. Competition reactions between NAD+ and pyruvate for reduction by formate catalysed by 4 showed a preference for reduction of NAD+. The

  deprotonated form of [(fluorene)FeCp]PF6 functions as an efficient cyclopentadienyliron (CpFe) transfer reagent to other cyclopentadienyls (Cp‘) to give mixed ferrocenes (CpFeCp‘). By using this method, many new mixed ferrocenes have been prepared, and one of the mixed ferrocenes has been used to make bi- and trimetallic compounds.

  Alkenyl N-pivaloylhydroxamates undergo an Ir(III)-catalyzed diamination of the alkene with simple exogenous secondary amines under extraordinarily mild reaction conditions. The regioselectivity of the diamination is controlled by the solvent and the electronics of the cyclopentadienyl (Cpx) ligand on Ir. On the basis of a set of mechanistic experiments, we propose that the relative rates of Ir(V)-nitrenoid
