Abstract Halogenation is one of the most important transformations in organic synthesis. Halogenated compounds are employed many reactions to prepare useful molecules. Many methods have been developed introduce halogens into different compounds. Visible light‐mediated efficient, low‐toxic, and mild‐condition applied for various chemistry transformations. Remarkably, there has an increasing development application visible light‐induced halogenation recent years. Herein, we present a comprehensive summary including chlorination, bromination, iodination under light irradiation since 2020.

A visible-light photoredox [3 + 2] cycloaddition reaction of arylidenecyclopropanes with olefins was developed, employing the readily available and commercially accessible TMSN3 as an efficient radical mediator. This method provides a convenient route to arylidenecyclopentanes from starting materials, is metal-free, features enhanced atom step economy, excellent selectivity, extensive substrate versatility, favorable functional group compatibility, structural diversity, mild conditions, which further enable late-stage diversification. DFT calculations elucidated that this transformation entails sequential generation, addition, ring-opening, cyclization, elimination steps.

Herein, we developed a novel radical cascade phosphorylation/cyclization strategy to access phosphorus-containing diazocine-fused carbazoles in moderate good yields, offering expanded opportunities for the exploration of biologically active molecules. This method features metal-free photochemical tandem, mild conditions, broad substrate scopes, and scale-up ability. Mechanistic experiments implied that this photocatalyzed reaction was realized by sequence EnT/SET/SET/radical addition/cyclization/SET/deprotonation processes.

Abstract Polycyclic indoles are prevailed in natural products, pharmaceuticals and biologically active compounds. Herein is described photo‐induced difluoromethylation‐cyclization of N ‐alkene tethered to synthesis tetrahydropyrido[1,2‐ a ]indole using 5‐((difluoromethyl)sulfonyl)‐1‐phenyl‐1H‐tetrazole as CF 2 H radical source. This photochemical reaction tolerates an array functional groups like ester, cyano, ketone, halide, ether, aldehyde heteocycles. Mechanistic experiments indicated that the difluoromethyl single electron transfer were involved.
