Abstract
A convenient and efficient procedure for the synthesis of benzo[4,5]thiazolo [2,3-c][1,2,4]triazoles has been developed via a tandem intermolecular C–N bond and intramolecular C–S bond formation sequence from o-bromo-arylisothiocyanates and aroylhydrazides. A series of benzo[4,5]thiazolo[2,3-c][1,2,4]triazoles were provided in excellent overall yields with 1 mol% CuCl2·2H2O/1 mol% 1,10-phenanthroline as the catalyst and water as the solvent.
