| Abstract: | A series of trarsition-metal hydroxamates M (L1)2～M(L6)2 were synthesized and characterized. Their catalytic activities in cumene oxidation to cumyl hydroperoxide (CHP) were examined. The influence of substituting groups and their terminal groups in the ligand on catalytic oxidation performance was discussed in comparison with unsubstituted analogue Cu(L7)2. The results show that Cu (L5)2 bearing terminal hydroxyl supported by sufficient long oxyethylene chain is the most excellent one among the total complexes. |
