Sulfur-containing organic molecules are of interest to scientists in several areas of research, from medicinal chemistry to material science. Among them, diaryl sulfides and their derivatives are important structural motifs in natural and synthetic molecules and have shown interesting biological and pharmaceutical activities. Moreover, they are precursors to other sulfur-containing compounds comprising higher-oxidation state-sulfur (sulfoxides, sulfones etc.), which have similar important bioactive properties. While previous synthetic methods have provided powerful tools for affording diaryl sulfides, still have some limitations such as sensitive/harsh reaction conditions or using prefunctionalized starting materials. Therefore, the development of novel and simple complementary strategies would be greatly valuable for the construction of Caryl-S bonds. Herein, a broad range of aryl thiols reacted with various aryl diazonium salts in the presence of eosin Y under air atmosphere via visible-light mediated organocatalytic process. This novel and environmentally friendly method provides an alternative route to established synthetic approaches to afford the desired products from easily available substrates in high yields.
