摘　　要：以溴素、甲硫醚、苯乙烯及其衍生物、不同的胺的衍生物,合成了一系列的氮杂环丙烷类化合物,并且通过红外光谱、核磁对产物的结构进行表征.以3-苯基-1-丙基氮杂环丙烷与CO_(2)作为模板反应,探究在双功能金属锌催化剂存在的情况下,对反应条件进行优化,筛选出最佳条件:CO_(2)压强为2 MPa、反应温度为130℃、催化剂与底物物质的量之比为1∶100、反应时间为8 h.在此最佳条件下,研究该催化体系催化其他氮杂环丙烷类物质和CO_(2)的环加成反应,并提出了环加成反应可能发生的机理.A series of aziridine compounds were synthesized with bromine,dimethyl sulfide,styrene and its derivatives,and different amine derivatives.The structure of the products was characterized by infrared spectroscopy and nuclear magnetism.Using 3-phenyl-1-propyl aziridine and CO_(2)as a template to react,it was explored to optimize the reaction conditions in the presence of a bifunctional metal zinc catalyst,the optimal conditions were selected as the CO_(2)pressure of 2 MPa.The reaction temperature was 130℃,the ratio of the amount of catalyst to substrate was 1∶100,and the reaction time was 8 h.Under these optimal conditions,the catalytic system was studied to catalyze the cycloaddition reaction of other aziridines and CO_(2),and the possible mechanism of the cycloaddition reaction was proposed.
