An unprecedented method for the conversion of (Z)-3-chloro-3-arylacrylic acids to corresponding benzoic acids by stirring in POCl3 at 80 °C is reported. The benzoic acids formed in situ undergo condensation with 4-amino-5-aryl-3-mercapto-1,2,4-

A new general synthesis of 4,5-disubstituted 2,4-dihydro-1,2,3-triazole-3-thiones is proposed.These heterocycles are obtained by the action of primary amines, aralhydrazines or aroylhydrazines on the thiosemicarbazones of esters.These last compounds are prepared by action of chlorhydrates of iminoesters on thiosemicarbazide in dimethylformamide.These thiosemicarbazones react also with strong acids, acid anhydrides and chlorides; by thermolysis and they give 2-amino-1,3,4-thiadiazole derivatives.Also, two derivatives of 1,2,4-triazolo-1,3,4-thiadiazole have been prepared.
