摘　　要：合成了水杨醛β-丙氨酸希夫碱复合双金属配合物(SACo/Cu、SACo/Mn、SACo/Fe),并用FT-IR,ICP,XPS进行了结构表征.以分子氧做氧化剂,考察了复合双金属配合物对环己烯选择性氧化催化性能,探论了温度、时间、催化剂用量与底物比、溶剂及添加剂等因素对该反应的影响.The Schiff base ligand（Sal-β-Ala） has been synthesized by the reactions between salilcyaldehyde and amino acids. Double-metal complexes（SACo/Cu, SACo/Mn, SACu/Fe） are prepared by coordination with double metal ions, such as Co^2＋/Cu^2＋, Co^2＋/Mn^2＋, and Cu^2＋/Fe^3＋. The structures are characterized by means of FT-IR, ICP, XPS. The catalytic abilities for oxidation of cyclohexene with oxygen at ambient conditions are studied. The influences of reaction temperature, reaction time, amounts of catalysts and additives on the oxidation of cyclohexene are investigated.
