[摘要]：Several 2-(benzylidenamino)thiophenols were electrochem. oxidized in MeOH contg. NaOAc as the supporting electrolyte, to afford the corresponding 2-arylbenzothiazoles. The reaction proceeded via intramol. cyclization involving the formation of a new bond between the benzylic C of the substrate and the S of the thiol group. Based on the yields, room temp. and the use of 2 equiv NaOAc relative to the substrate as the supporting electrolyte were found to be the optimal reaction conditions. The electrooxidn. presumably involves a 2-electron oxidn. process.
