A novel approach towards synthesis of benzothiazoles and benzimidazoles: Eosin Y-catalyzed photo-triggered C–S and C–N bond formation

Abstract

A novel metal-free and environment-friendly approach for synthesizing biologically important moieties, benzothiazoles and benzimidazoles, using photoredox catalyst Eosin Y, ethanol:water as a green solvent and atmospheric air as an oxidant has been developed.
