Iron catalyzed efficient synthesis of 2-arylbenzothiazoles from benzothiazole and olefins using environmentally benign molecular oxygen as oxidant

Abstract

A novel protocol for iron catalyzed arylation of benzothiazole with olefins has been developed using molecular oxygen as a greener oxidant. The reaction worked smoothly using inexpensive and easily available iron as a catalyst for the synthesis of 2-arylbenzothiazole derivatives in good to excellent yields.
