O－烷基苯基硫代膦酰取代硫脲的合成（Ⅲ）──含P─C键化合物的研究

Synthesis of O-Alkylphenylthioureidophosphonothioates──A Study of the Compounds Including P-C Bonds

利用Ｏ－烷基苯基硫代磷酸酸异硫氰基酯与胺与胺的加成反应，合成了两系列Ｏ－烷基苯基硫代磷酰取代硫脲化合物，经元素分析、ＩＲ和＾１ＨＮＭＲ确定了它们的结构，并进行了除草活性的测试。

By the reactions of O-alkylphenylthiocyanatidophosphonothioates with amines,two series of O-alkylphenylthioureidophosphonothioates were prepared.The structures of these compounds have been confirmed by IR, NMR and elementary analysis.The results from the biossay show that these compounds have no significant herbicidal activity.
