Abstract

A series of 3-aryl naphto[2',3':4,5]thiazolo[3,2-<i>b</i>-1,2,4-triazolo-5,10-diones (<i>V</i>) have been prepared by the condensation of bromo lawsone (<i>I</i>) with 5-mercapto-3-substituted 1,2,4-triazole (<i>II</i>) followed by cyclization of the resulting uncyclized products (<i>IV</i>) with alkohol and sulfuric acid. The products are identical with the condensation products of 2,3-dichloro naphthoquinone (<i>III</i>) with 5-mercapto-3-substituted 1,2,4-triazoles in the presence of anhydrous alcohol containing fused sodium acetate.
