In this study, a novel approach that combines photoinduced electron transfer (ET) with hydrogen atom (HAT) has been introduced for the selective β-C(sp3)–H pyridination of carbonyl compounds. This method is notable its absence transition metals and ability to function under benign reaction conditions, resulting in range pyridinated derivatives consistently moderate good yields. The significance technique further underscored by potential late-stage functionalization pharmaceutically significant molecules. Mechanistic investigations confirmed proceeds via radical-mediated pathway.
