摘　　要：Polymer-bound Schiff-base ligand (PS-Sal-Cys) was prepared from the polystyrene-bound salicylaldehyde and L-cysteine, its complex (PS-Sal-Cys-Mn) was also synthesized. The polymer ligand and its complex were characterized by infrared spectra (IR), small area X-ray photoelectron spectroscopy (XPS), and inductively coupled plasma-atomic emission spectro (ICP-AES). In the presence of complex, cyclohexane can be effectively oxidized by molecular oxygen without a reductant. The major products of the reaction are 2-cyclohexen-1-ol, 2-cyclohexen-1-one, and 2-cyclohexen-1-hydroperoxide, which is different from the typical oxidation of cyclohexene. The mechanism of cyclohexene oxidation is also discussed.Polymer-bound Schiff-base ligand （PS-Sal-Cys） was prepared from the polystyrene-bound salicylaldehyde and L-cysteine, its complex （PS-Sal-Cys-Mn） was also synthesized.
