Abstract Quaternary pyridinium compounds are valuable intermediates in organic synthesis, which have gained immense popularity the synthetic community. The application of transition metal or photoredox catalysis transforming quaternary into various C−C and C−X bonds is well established. A majority these methods require high temperatures, expansive catalysts, delicate conditions for successful execution. On other hand, use metal‐free photocatalysis‐free strategies constructing using derivatives has been sought‐after. In this context, electron‐donor‐acceptor (EDA)‐complex reactions emerged as a state‐of‐the‐art methodology, do not any photocatalyst their EDA‐complex photochemistry takes advantage electron‐acceptor ability derivatives, can quickly generate radical precursor via deaminative process. These newly generated useful several transformations. We hereby, review, discuss an area major progress mediated involving with mechanism, substrate scope, limitations. magnified image

An efficient strategy for the preparation of aryl phosphonates via blue-light-promoted single electron transfer process an EDA complex between phosphites and thianthrenium salts has been demonstrated. The corresponding substituted were obtained in good to excellent yields, byproduct thianthrene can be recovered reused quantity. This developed method realizes construction through indirect C-H functionalization arenes, which potential application value drug discovery development.

A simple and practical electron donor-acceptor (EDA) strategy to synthesize various 3-alkylated coumarins from easily available naturally abundant carboxylic acids under photocatalyst-, oxidant-, additive-free mild conditions is reported. Using Na2S as the catalytic donor, a series of primary, secondary, tertiary carbon radicals can be efficiently generated, EDA complex regenerated without an alkaline additive.

The twelve principles of green chemistry illuminate the pathway in direction sustainable and eco-friendly synthesis, marking a fundamental shift synthetic organic paradigms. In this realm, harnessing power visible light for difunctionalization various skeletons without employing any external oxidant or reductant, specifically termed as redox-neutral difunctionalization, has attracted tremendous interest from chemists due to its low cost, easy availability environmentally friendly nature contrast traditional metal-catalyzed difunctionalizations. This review presents an overview recent updates on visible-light-induced reactions with literature coverage up May 2024.
