Visible Light and Triselenium Dicyanide (TSD): New Horizons in the Synthesis of Organic Selenocyanates

The cover feature shows an industrial environment highlighting the production line conveyor belts on which substrates are inserted into a “blue light box” and are converted to the desired products. In their Research Article (DOI: 10.1002/chem.202301934), F. Penteado, E. J. Lenardão and co-workers report a sophisticated application of triselenium dicyanide (TSD) in a light-mediated transformation triggered by the generation of Se-centered radical species. By exploiting this activation strategy, a library of α-carbonyl selenocyanates and 2-phenylimidazo[1,2-a]pyridine derivatives was satisfactorily prepared under mild reaction conditions.
