Sažetak
A mild and efficient one-pot visible light irradiated synthesis of 2-aminobenzothiazole 4(a–l) from arylisothiocyanate 1(a–l) and secondary amines 2 have been reported in presence of eosin Y as an organophotoredox catalyst at room temperature under aerobic condition. This synthesis includes application of air and visible light as inexpensive, readily available, high atom economy, non-toxic and sustainable regents.
