Rose‐Bengal‐Photocatalyzed Cross‐Dehydrogenative Coupling Reactions under Visible Light

Abstract

AbstractOver the past few years, organic chemistry has used the organic dye rose bengal‘s ability to absorb visible light. In present‐day research, the innovation of environmentally friendly processes for carbon‐carbon/carbon‐heteroatoms (Nitrogen, Oxygen, Sulphur, and Phosphorus) bond formation has great importance. The photocatalyzed cross‐dehydrogenative coupling (CDC) reactions using rose bengal (RB) is a promising technique for creating carbon‐carbon/carbon‐heteroatom bonds directly from readily available compounds. Our review focuses on the current advancement in rose bengal that uses photocatalyzed carbon‐carbon/carbon‐heteroatom bond‐making reactions to synthesize various important organic molecules via CDC reactions.
