Visible-light-induced direct hydrodifluoromethylation of alkenes with difluoromethyltriphenylphosphonium iodide salt

Xiaojian Ren et al.

Summary: Photoredox-catalyzed hydrodifluoromethylation is an effective method for introducing difluoromethyl groups into organic molecules. This study presents a simple alternative approach for the hydrodifluoromethylation of alkenes by photoactivating difluoromethyl-triphenylphosphonium iodide salt, without utilizing photocatalysts or additives. Mechanistic studies provide insights into the reaction pathway.

Visible-light-induced N-heterocyclic carbene mediated cascade transformation of N-alkenoxypyridinium salts

He Sheng et al.

Summary: In this study, a photoinduced NHC-mediated functionalization of N-alkenoxypyridinium salts with various nucleophiles was developed. A cascade radical-radical coupling/nucleophilic substitution reaction was proposed for the synthesis of α-iodo ketones. This method allows for the reaction with diverse nucleophiles under mild conditions.

Visible-Light-Induced Selective Photolysis of Phosphonium Iodide Salts for Monofluoromethylations

Qiang Liu et al.

Summary: The sigma-hole effect is utilized to facilitate the photolysis of phosphonium iodide salts, selectively generating fluoromethyl radicals, allowing for mono-, di-, and trifluoromethylation reactions using fluoromethylphosphonium salts.

The wavelength-regulated stereodivergent synthesis of (Z)- and (E)-1,4-enediones from phosphonium ylides

Mei Wang et al.

Summary: The study reports a wavelength-regulated, methylene blue organic dye-catalyzed method for the stereodivergent synthesis of (Z)- and (E)-1,4-enediones from stabilized phosphorous ylides. The method shows broad substrate and functional group tolerance. Mechanistic studies suggest singlet-oxygen-promoted (E)-alkene formation via a possible phospha-1,2-dioxetane intermediate, followed by a blue-LED triggered (E) -> (Z) isomerization reaction.
