“…12 In particular, impressive progress has been made with Earth-abundant iron salts as LMCT catalysts under the irradiation of purple or blue light. 13 With our continuous interest in sustainable organic synthesis enabled by photo-/electro-chemistry, 14 we wish to report herein a visible-light induced selenocyclization strategy for the facile synthesis of 3-selenylindoles, wherein simple FeBr 3 was employed as both a photo-induced LMCT catalyst and a Lewis acid catalyst (Scheme 1b). To the best of our knowledge, such a photo-induced, Fe-based catalytic mode has not been proposed before.…”

Aryl radicals are important intermediates in organic synthesis. The generation of these reactive species via direct decarboxylation of inexpensive and readily available aromatic carboxylic acids is an attractive goal. However, such a process intrinsically exhibits high energy barriers to overcome, which in consequence usually require precious metal catalysis, stoichiometric oxidants and harsh conditions, suffering from limitations such as poor functional group tolerance and low atom economy. In recent years, visible‐light‐induced photochemical reactions have provided new approaches to address this challenge. Three major strategies have been introduced in this emerging field: 1) one‐pot in‐situ activation of benzoic acids to generate intermediates such as benzoyl hypobromites or hypoiodites; 2) the use of specialized photocatalysts like biphenyl/1,4‐dicyanobenzene to promote decarboxylation through photo‐induced electron transfer or charge transfer processes; 3) photo‐induced LMCT (Ligand‐to‐Metal Charge Transfer) strategy where copper or iron salts coordinate to the carboxylate anion and generate aromatic radicals upon visible light excitation. On the basis of these three strategies, this review will systematically summarize the development of visible‐light‐induced direct decarboxylative functionalization of aromatic carboxylic acids, focusing on the reaction mechanism and substrate scope, and discuss their prospects in organic synthesis.

Germanium (Ge), a congener of carbon, possesses unique properties that hold extensive potential for applications across multiple domains. Recent years have seen significant progress in the development of carbon‐germanium bond formation strategies, particularly those for more challenging C(sp3)‐Ge bonds. This review systematically summarizes the recent advances in C(sp3)‐Ge bond forming methodologies, with particular emphasis on (1) the versatility of transition‐metals, including iron, nickel, copper, rhodium and palladium, as catalysts in broadening reaction scope and controlling selectivity; (2) the powerfulness of organic photocatalysis in achieving mild and selective bond formation, and (3) the sustainability of catalytic electrosynthesis in facilitating chemical oxidant‐/reductant‐free conversions. Additionally, examples of (4) non‐catalytic strategies are also discussed. The representative scopes, as well as mechanistic proposals, of these protocols are highlighted. Through an overview on the current state of research, this review aims to offer insights into the catalytic construction of C(sp3)‐Ge bonds, and provide perspectives on future research directions to address the current challenges.
