  摘要：

  A series of dioxidomolybdenum(VI) complexes, [(MoO2L1-6)-O-VI] (1-6) and [(MoO2L1-6)-O-VI(solv)] (1a-6a) {where solv (solvent) = DMSO (1a, 3a, 5a and 6a) and H2O (2a and 4a)) have been synthesized using thiosemicarbazone ligands, H2L1-6. Furthermore, six monooxidomolybdenum(IV) complexes [(MoOL1-6)-O-VI(N-N)] (7-12) {where co-ligand (N-N) = 2,2'-bipyridine (bipy) (7,10 and 11) and 1,10-phenanthroline (phen) (8, 9 and 12)) have also been synthesized from the corresponding Mo(VI) precursors, [(MoO2L1-6)-O-VI] (1-6) by oxygen atom transfer (OAT) reaction. Complexes have been characterized by conventional methods, including X-ray crystallography, and DFT (density functional theory) calculations. OAT reactivity of Mo(VI) and Mo(IV) complexes have been successfully established through the formation of OPPh3 and Me2S. These OAT products have been characterized by P-31 NMR (OPPh3), UV-Vis spectroscopy and GC-MS (Me2S) and DFT simulations supported this finding through the prediction of Delta G(sol)(tot) for the reaction of oxygen atom transfer. DFT methods suggested that the oxygen atom transfer from [(MoO2L)-O-VI] species to PPh3 to give [(MoOL)-O-VI(bipy)] and from DMSO to [(MoOL)-O-IV(bipy)] to yield [(MoO2L)-O-VI] is strongly favored, whereas the formation of mu-oxido dimer [(Mo2O3L2)-O-V], is much less probable.
