摘　　要：通过１－苯基－３－对甲苯磺酰基脲与亚磷酸三苯酯和取代苯甲醛在甲苯中进行的类Ｍａｎ－ｎｉｃｈ反应合成１－对甲苯磺酰基－２－苯氧基－２－氧代－３－芳基－４－苯基－１，４，２－二氮磷杂环戊－５－酮．化合物的结构经元素分析、ＮＭＲ、ＭＳ及部分化合物的红外光谱所证实，对合成过程中所涉及到的副反应进行了初步探讨，生物测定实验表明，某些产物具有良好的选择性除草活性。A series of 1-(p-toluenesulfonyl)-2-phenoxy-3-aryl-4-phenyl-1,4,2-diazaphospholidin-5-one-2-oxides (2) has been synthesized by the. Mannich-type reaction of 1-phenyl-3- (ptoluenesulfonyl) urea(1), substituted benzaldehydes and triphenyl phosphite in anhydrous toluene. The side reactions were discussed. The structures of new compounds were characterized by ￣1H NMR, ￣(31)p NMR, elemental analysis, MS and IR spectra. The results of preliminary bioassay showed that the compound 2 possesses good selective herbicidal activity against rape.
