合成了含NOS配位原子的三齿西夫碱的镍配合物,并用红外,核磁,元素分析和晶体衍射进行了表征.发现此类配合物在相转移试剂存在下以次氯酸钠为氧源对烯烃的氧化具有较好的催化活性,研究表明配体结构和反应条件对反应结果具有较大影响,在优化条件下,采用该类催化剂催化苯乙烯氧化可得到54%环氧化产率.

The nickel complexes with tridentate Schiff-base ligands containing NOS donor atoms were synthesized and char-acterized by IR,1H NMR, elemental analysis and X-ray crystallography. They were found to be active catalysts for styrene oxidation with NaOCl in the presence of phase transfer reagent. The influences of ligand structure and reaction conditions were studied, resulting in the highest yield of styrene epoxide as 54%.
