文摘

Two novel oxomolybdenum(V)-trispyrazolylborate complexes [(TpMoO)(μ₂-O)₂(MoOTp)](Tp = tris(pyrazolyl)borate) (1) and [(Tp^4IMoOCl)(μ-O)(MoOClTp^4I)](Tp^4I = tris(4-iodinpyrazolyl)borate) (2) were synthesized and characterized by elemental analysis, IR spectra and single-crystal X-ray diffraction. Their catalytic performances in cyclohexane (Cy) oxidation were studied. It is found that the catalytic performances of molybdenum(V) complexes 1 and 2 were far more better than the molybdenum(VI) complexes with the similar structure. The influence of the amount of H₂O₂, HNO₃ and the solvents on the Cy oxidation were investigated too.
