5-Aroylamino-2H-1,2,4-thiadiazol-3-ones 3 were obtained from the corresponding 1-aroyl-2-thiobiurets 2 by oxidative cyclization with bromine. 5-Aroylamino-2H-1,2,4-thiadiazol-3-ones 3 can exist in two tautomeric forms a lactam form and a lactim form. On the basis of the 13C nmr spectra and additional experimental information, it has been established that the stable form, in which these compounds exist
5 -Aroylamino -2- ħ -1,2,4-噻二唑-3-酮3由相应的1-芳酰基-2- thiobiurets得到2通过用溴氧化环化。5-芳酰基氨基-2 H -1,2,4-噻二唑-3-酮3可以以两种互变异构形式内酰胺形式和内酰胺形式存在。根据13 C nmr光谱和其他实验信息,已经确定存在这些化合物的稳定形式为内酰胺形式。
