Convenient synthesis of benzo[4,5]thiazolo[2,3-c][1,2,4]triazoles with 1 mol% CuCl2·2H2O as catalyst in water

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.

Photochemical synthesis of s-triazolo[3,4-b]benzothiazole and mechanistic studies on benzothiazole formation

A general photochemical synthesis of s-triazolo[3,4-b]benzothizoles from 4,5-disubstituted 1,2,4-triazole-3-thione is described. Steady photolysis, quantum yield determination, and laser flash photolysis experiments have been carried out. An intermolecular electron transfer mechanism has been proposed.

Thallium(III) salts mediated oxidative cyclization of arenecarbaldehyde benzothiazol-2-ylhydrazones to bridged head nitrogen heterocycles

Oxidation of arenecarbaldehydebenzothiazol-2-ylhydrazones (4) with thallium (III) acetate in refluxing acetic acid, thallium (III) acetate and thallium (III) nitrate in acetonitrile in presence of p-toluene sulphonic acid afforded 3-aryl-1,2,4-triazolo [3
