摘  要:
先将2-噻唑烷酮与O,O'-二乙基硫代磷酰氯进行缩合反应生成O,O'-二乙基-2-氧代-1,3-噻唑烷-3-基硫逐磷酸酯,该硫逐磷酸酯再与二甲胺反应生成相应硫代磷酸酯铵盐,然后与溴代仲丁烷进行烷基化反应得到噻唑磷。反应总收率达到36%,产品含量大于80%。产物结构经IR、1HNMR和MS表征。

摘  要:
Fosthiazate was synthesized by condensing 2-thiazolidinone with O,O'-diethylthio- phosphonochloride,and then alkylating the resulting O,O'- diethyl-2-oxo-1,3-thiazolidine-3-thiophosphate with dimethylamine, followedby direct alkylation of the ammonium salt with 2-bromobutane. Total yield of fosthiazate was as high as 36% andproduct purity was >80%. The structure of the product was identified by IR, 1H-NMR and MS.
