A merger of heterogeneous polycrystalline WSe2 semiconductor photocatalysis and homogeneous ferrocene redox catalysis for the cascade radical coupling-annulation reactions was established. In redox-mediated photocatalysis, can improve separation photogenerated hole–electron pairs on by consuming hole via formation a cation, which triggered molecular transformations. Various benzo[e]imidazo[1,5-c][1,2,3]oxathiazine 5,5-dioxides were formed through semiheterogeneous three-component reaction N-sulfonyl ketimines, N-arylglycines, formaldehyde.

With both ferrocene and air as the redox catalysts, for first time, low-cost natural ilmenite (FeTiO3) was successfully used photocatalytic bond formations. Under assistance of a traceless H-bond, HCHO methylene reagent, variety imidazo[1,5-a]quinoxalinones were semi-heterogeneously photosynthesized in high yields with good functional group compatibility.

Comprehensive Summary Organic fluorine compounds are ubiquitous and pivotally important organic molecules, yet their activation transformation have long been a formidable challenge due to the high energy low reactivity of C—F bonds. electrosynthesis, an environmentally benign synthetic method in chemistry, enables myriad chemical transformations without need for external redox reagents. In recent years, electrochemistry has emerged as powerful tool achieving bonds fluorine‐containing compounds. This review aims succinctly recapitulate latest advancements electrochemical defluorinative delve into reaction design, mechanistic insights, developmental prospects these methods. Key Scientists 1959, Lund was first pioneer electroreduction CF 3 CH group. Electrochemistry lately provided new opportunities efficient conversion fluorides. 2020, Zhou coworkers discovered carboxylation α‐CF alkenes. Lambert colleagues reported electrophotocatalytic amination aryl Electrochemical hydrodefluorination trifluoromethylketones developed by Lennox 2021. same year, Wang Guo disclosed radical alkylation alkenes with Katritzky salts alkyl precursors. Subsequently, Wu Liao described transition‐metal‐free, site‐selective arylation polyfluoroarenes (het)arenes using paired electrophotocatalysis. 2023, numerous efforts were made achieve bond activation. Xia organoboron‐controlled chemoselective sequential (deutero)hydrodefluorination trifluoroacetamides.
