摘　　要：通过１－苯基－３－对甲苯磺酰基硫脲（１）与亚磷酸三苯酯和取代苯甲醛在甲苯中进行的类Ｍａｎｎｉｃｈ反应合成１－对甲苯磺酰基－２－氧代－２－苯氧基－３－芳基－１，４，２－二氮磷杂环戊－５－硫酮（２）．本文对合成过程中所涉及到的副反应进行了初步探讨，初步的生物活性测定结果表明，化合物２具有一定的除草活性。Phenyl-3-(p-toluenesulfonyl) thiourea was reacted with triphenylphosphite and substituted benzaldehydes to give 1-(p-toluenesulfonyl)-2-oxo-2-phenoxy-3-aryl-1,4,2-di-azaphospholidin-5-thiones in anhydrous toluene. The by-reactions of the preparation process were discussed. The structures of new compounds were confirmed by elementary analysis,￣1HNMR, ￣3FPNMR, MS and IR spectra. The results of preliminary bioassay show that they possess a herbicidal activity at 1.5kg/ha in post-emergent tests against six kinds of plants including Barnyard-grass, Oat, Rape, and Alfalfa,etc.
