Abstract A copper-catalyzed reaction of benzothiazole and readily available toluene derivatives has been disclosed. This protocol is proposed to proceed through the oxidation of toluene and ring opening of benzothiazole, thus providing a new pathway for the synthesis of 2-arylbenzothiazoles. A copper-catalyzed reaction of benzothiazole and readily available toluene derivatives has been disclosed. This

feedstocks under mild conditions is attractive and highly desirable in pharmaceutical and natural product synthesis. Minisci-type cross dehydrogenative coupling between heteroarenes and C(sp3)–H bonds offers direct access to these important scaffolds in a step-economic manner. Herein, assisted by stop-flow microtubing reactors, an operationally simple protocol for the visiblelight-induced hydrogen-evolution
