Oxidative cyclization of thiobenzanilides to benzothiazoles using N-Benzyl-DABCO tribromide under mild conditions

Abstract

N-benzyl-DABCO tribromide, a stable, crystalline organic ammonium tribromide (OATB), have been used as an alternative electrophilic bromine source for the efficient oxidative cyclization of thiobenzanilides to the corresponding benzothiazoles under mild conditions. © Georg Thieme Verlag Stuttgart.
