“…The findings of this study significantly expanded the synthetic toolbox for accessing functionalized coumarin derivatives and related nitrogen-containing heterocycles, opening up exciting possibilities for their diverse applications in other fields. Similarly, the regioselective photodecarboxylative C–H alkylation of 2 H -indazoles and azauracils using NaI/PPh 3 as mediators and redox esters 3 was reported by the research groups of Murarka [ 18 ] and Fan [ 19 ], respectively.…”

Photoredox catalysis plays a crucial role in contemporary synthetic organic chemistry. Since the groundbreaking work of Shang and Fu on photocatalytic decarboxylative alkylations in 2019, a wide range of organic transformations, such as alkylation, alkenylation, cyclization, amination, iodination, and monofluoromethylation, have been progressively achieved using a combination of iodide and PPh3. In this review, we primarily focus on summarizing the recent advancements in inexpensive and readily available iodide/phosphine-mediated photoredox radical transformations.
