ARS-TiO2 catalyzed direct functionalization of sp2 C-H bonds toward arenes and heteroarenes containing thiocyanate and 2-aminobenzothiazole under visible light irradiation

Abstract

ARS-TiO2 photocatalyst has been prepared by simple method. The synergic effect of ARS and TiO2 in the photocatalyst system has catalyzed direct C-H functionalization of sp2 C-H bonds toward thiocyanation and cyclization reactions. A majority of structurally diverse aromatic and heteroaromatic compounds (2-phenylamino-thiazole, phenol, aniline, indole and pyrrole derivatives) treated with thiocyanate anion at room temperature. Herein, the first report for thiocyanation of phenol and synthesis of 2-aminobenzothiazole derivatives under visible light has been developed
