摘　　要：应用固相合成方法合成了氯甲基聚苯乙烯(氯球)担载的1-6代聚酰胺-胺(PAMAM)树状分子镍配合物,将此类配合物用用作在无溶剂情况下分子氧氧化环己烯的催化剂,对其催化性能进行了研究.结果表明,此类配合物对环己烯的氧化反应具有较好的催化活性,反应以2-环己烯醇、2-环己烯酮、和7-杂氧二环[4,1,0]环庚烷-2-酮(3)为主要产物.催化剂制备方法简单且可回收和重复利用.Chloromethyl polystyrene supported dendritic nickel complexes were prepared by solid phase synthesis methodology.The complexes were characterized by IR spectroscopy and ICP.These complexes all show promising catalytic activities for the oxidation of cyclohexene with molecular oxygen without solvent.The oxidation gives 2-cyclohexen-l-ol,2-cyclohexen-l-one and 7-oxabicyclo[4,1,0] heptan-2-one as major products.The catalysts could be obtained in a simple and efficient manner.Moreover, the catalysts can be recycled for several times without the obvious decrease of the activity.
