PHOTOCHEMICAL SYNTHESIS OF S-TRIAZOLO[3,4-B]BENZOTHIAZOLE AND MECHANISTIC STUDIES ON BENZOTHIAZOLE FORMATION

Abstract

A general photochemical synthesis of s-triazolo[3,4-b]benzothiazoles 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 intramolecular electron transfer mechanism has been proposed
