Dyes as Visible Light Photoredox Organocatalysts

Tomorrow always dyes! Organic dyes (e.g., Rose Bengal, Eosin Y) have been recently used as versatile photoredox organocatalysts in place of metal complexes (e.g., Ru2+ salts). Accordingly, photoinduced electron transfer reactions induced by excited dyes were exploited in various synthetic processes. The reactions were performed under metal-free conditions and visible light irradiation.
