Summary:[Display omitted] •An efficient and convenient synthesis of benzothiazoles from 2-aminothiophenols and aldehydes via visible-light irradiation.•Aromatic, heteroaromatic and aliphatic aldehydes are applicable.•A radical reaction pathway via the diaryl disulfide intermediates is proposed. A visible-light-promoted synthesis of benzothiazoles from 2-aminothiophenols and aldehydes has been developed. A wide range of aromatic, heteroaromatic and aliphatic aldehydes were successfully applied. The benzothiazole products were prepared in good yields. The reaction was carried out in the absence of transition-metal catalysts and extra additives. A radical reaction pathway was proposed.
