The reaction of N,N-disubstituted thioamide–bromine adducts with unsubstituted thioamide, followed by treatment with triethylamine, affords novel N′-thiobenzoylamidines along with smaller amounts of secondary products. A mechanism is proposed for the formation of the amidines. The results give an insight into the initial steps of the mechanism by which thioamides are converted into 1,2,4-thiadiazoles
的反应Ñ,Ñ二取代的硫代酰胺-溴加成物与未取代的硫代酰胺,随后用三乙胺处理,得到新颖Ñ '与较少量的副产物的沿-thiobenzoylamidines。提出了形成the的机制。结果使人们深入了解了将硫酰胺转化为1,2,4-噻二唑的机理的初始步骤。
