摘　　要：合成了新型的环己醇氧化催化剂六齿配位5-氯-7-碘-8-羟基喹啉锰配合物,并用傅立叶变换红外光谱及元素分析对其结构进行了表征。在反应温度(25～30)℃、催化剂用量0.002 mmol、溶剂丙酮用量2 mL和反应5 h条件下,反应转化数(TON)达1 409,环已酮选择性为100%,催化剂可循环使用。A new manganese complex with hexadentate mode, 5-chloro-7-iodo-8-quinoliolato Mn m, was prepared and characterized by elemental analysis and IR. Oxidation of cyelohexanol to cyelohexanone with hydrogen peroxide over the complex catalyst was studied. The influence of reaction temperature, reaction time, catalyst and solvent dosage was investigated. The turnover number and selectivity to cyclohexanone were 1 409 and 100%, respectively, under the optimal condition.
