Abstract

A new, highly efficient procedure for the synthesis of benzothiazoles from easily available N- benzyl-2-iodoaniline and potassium sulfide has been developed. The results show copper- catalyzed double C–S bond formation via a traditional cross-coupling reaction and an oxidative cross-coupling reaction.
