摘要： 报道了合成S-烷基S-烷基(芳基)二硫代磷酸衍生物的一种便利的新方法。O,O-二烷基S-烷基(芳基)二硫代磷酸酯与三氯氧磷发生氯化反应的同时,伴随着P=S键异构成P—S键,生成S-烷基S-烷基(芳基)二硫代磷酰氯,在碱存在下进一步与各种亲核试剂反应,得到S-烷基S-烷基(芳基)二硫代磷酸衍生物。

Abstract: Eleven compounds, among which nine are new compounds, of S-alkyl S-alkyl (aryl) dithiophosphpric acid derivatives have been synthesized by using a new convenient method which is based on the isomerization/chlorination of S-alkyl (aryl) O,O-dialkyl dithiophosphate with phosphorus oxychloride to give S-alkyl S-alkyl (aryl) phosphorochloridodithiolate.Then, this phosphorochlo-ridodithiolate reacts with various nuclosphiles, such as alcohol, phenol, mercaptan, thiophenol, ammonia in the presence of acid-binding agent to obtain S-alkyl S-alkyl (aryl) dithiophosphoric acid derivatives, such as S-alkyl S-alkyl (aryl) O-alkyl(aryl) phosphorodithiolate, S-alkyl S,S-dialkyl (aryl) phosphorotrithiolate, S-alkyl S-alkyl (aryl) phosphoramidodithiolate.The results of the tests in biological activity show that these compounds prepared possess a certain insecticidal or fungicidal activ-itiy.
