摘　　要：首次采用硒粉作催化剂，三乙胺作助催化剂，用芳香族硝基化合物作原料进行还原羰基化反应，合成Ｎ，Ｎ′－二芳基脲。研究了硒的用量、压力、温度、时间和水量的变化对Ｎ，Ｎ′－二苯基脲产率的影响。iarylurea has been synthesized conveniently from aromatic nitro-compound by reductive carbonylation, using selenium powder as the catalyst and trlethyl amine as the promoter for the first time. The effects of time, temperature, pressure and the amount of water and selenium catalyst were also studied.
