Electrooxidative Cyclization of Benzylidenaminothiophenols to the Corresponding 2-Arylbenzothiazoles Okimoto, Mitsuhiro Yoshida, Takashi Hoshi, Masayuki Hattori, Kazuyuki Komata, Masashi Tomozawa, Kenta Chiba, Tomohito Several benzylideneaminothiophenols were electrochemically oxidized in methanol containing sodium acetate as the supporting electrolyte, to afford the corresponding 2-arylbenzothiazols. The reaction proceeded via intramolecular cyclization involving the formation of a new bond between the benzylic carbon of the substrate and the sulfur of the thiol group. Based on the yields, room temperature and the use of two equivalents of sodium acetate relative to the substrate as the supporting electrolyte were　found to be the optimal reaction conditions. The electrooxidation presumably involves a two-electron oxidation process.
