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.

Study of oxidative cyclization using PhI(OAc)2 in the formation of benzo[4,5]thiazolo[2,3- C ][1,2,4]triazoles and related heterocycles - Scope and limitations

A one-pot, two-step reaction for the synthesis of benzo[4,5]thiazolo[2,3-c] [1,2,4]triazoles and related heterocycles under mild conditions was herein developed. The key step of this transformation is an oxidative cyclization employing PhI(OAc)2/sub
