摘要
Ｏ－乙基－Ｎ－异丙基硫代磷酰硫脲衍生物与氯乙酰氯、二氯乙酰氯及三氯乙酰氯，在碱存在下可发生关环反应，得到相应的噻唑啉酮类衍生物。讨论了不同试剂及反应条件对产物结构的影响，而Ｏ－乙基－Ｎ－异丙基硫代磷酰硫脲与氯乙醛关环，则生成相应的噻唑衍生物。所有化合物经元素分析、１ＨＮＭＲ、ＩＲ及ＭＳ证实，其中部分化合物显示出一定的除草活性。
O-ethyl-N-isopropyl thiophosphoryl substituted thioureas reacted with chloroacetyl chloride,dichloro acetyl chloride,trichloro acetyl chloride and chloroethanal, in the presence of base to give corresponding thiazolidine and thiazole derivatives,respectively.It was found that different products were due to different structures of reactive reagents, and the effect of reactive condition on the assign of products was studied. The result of bioactivities indicates that some of compounds have herbicidal activity.
