“…Carboxylic acids as starting materials are not only abundant, generally stable, and readily accessible in great structural diversity, and have also drawn much attention for their application as versatile radical precursors such as alkyl, aryl, carboxylic, and particularly acyl radicals (Mandal et al, 2018;Wang et al, 2019;Hu et al, 2020b;Chan et al, 2022;Kitcatt et al, 2022;Yan et al, 2022). Recently, an elegant strategy that combines photoredox catalysis and phosphoranyl radical-mediated deoxygenation makes it possible to form acyl radicals from carboxylic acids, providing streamlined access to structurally diverse ketones (Zhang et al, 2017;Stache et al, 2018).…”
