摘　　要：以二苯胺和对硝基苯胺为原料,通过胺基的重氮化碘代、乌尔曼反应、硝基还原和胺基的再次重氮化碘代反应,合成得到了三芳胺类星状爆炸物中间体N,N-二苯基-4-碘代苯胺。此一系列反应条件较温和,产率较高,中间体和产物纯化处理较容易。使用核磁和质谱对其结构进行了表征,并测得它在三氯甲烷溶液中的紫外吸收光谱和晶体的光致发光光谱。The recent development of catalysts for hydrogenation of chloronitrobenzene to chloroaniline was reviewed. The characteristic properties of noble catalysts （noble metal clusters or supported noble metal catalysts）, Raney nickel and amorphous alloy catalysts were analyzed and compared. Noble catalysts have high activity and selectivity, and the reaction conditions are mild. Raney nickel is of low price and used widely;however, in order to inhibit dehalogenation, some toxic promoters such as bases were used and extra processing steps had to be adopted to remove them. Amorphous alloy is a kind of new materials and has good catalytic performance, while its thermal stability has to be improved.
