Owing to the excellent biological activities of quinolines and organic chalcogenides, organosulfenylquinolines, which contain both sulfur and quinolinones, may have potential biological activity. To solve the existing problems for their generation, an electrochemical annulation/thiolation of o ‐vinylphenyl isocyanides with diorgano disulfides to give 2‐sulfenylquinolines is reported. As compared to previous methods, this procedure has the advantages of mild reaction conditions, good substrate applicability, and environmental friendliness.
