摘要:
The synthesis, characterization and spectroscopic properties of a group of Mo(VI) complexes having thiocarboxylate ligands of type [(MoO2)-O-VI(O2CC(S)MePh-X)(2)](2-) have been reported (X = H,p-Me,p-Cl). The peak potential for the Mo(VI) reduction increases according to the electron-donor ability of X (Me > H > Cl), Reaction of these Mo(VI) complexes with their own free ligands has been studied by ESR and UV-Vis spectroscopy, yielding the monomeric [(MoO)-O-V(O2CC(S)MePh-X)(2)](-) as unique complex products. The kinetic study of this oxidation reaction has also been investigated. (C) 1998 Elsevier Science S.A.
