Visible-light-induced C–S bond formation in the synthesis of 2,4-disubstituted thiazoles through cascade difunctionalization of acetophenone: a greener approach

A novel approach for the synthesis of 2,4-disubstituted thiazoles from methyl aryl ketones, N -bromo-succinimide (NBS), and thioamide in water as a green reaction medium through visible-light irradiation is reported.
