Dual Ni/photoredox-catalyzed asymmetric cross-coupling to access chiral benzylic boronic esters
Nature Communications, 2021 Metallaphototoredox catalysis has been rarely applied to reductive cross-couplings, in contrast to typical redox-neutral methods. Here, the authors report a mild Ni/photoredox-catalyzed reductive cross-coupling of aryl iodides and α-chloroboranes ...

Trifluoromethylation of Allylsilanes under Photoredox Catalysis
Organic Letters, 2013 A new catalytic method to access allylic secondary CF3 products is described. These reactions use the visible light excited Ru(bpy)3Cl2·6H2O catalyst and the Togni or Umemoto reagent as the CF3 source. The photoredox catalytic manifold delivers enantioenriched allylic trifluoromethylated products not accessible under Cu(I) catalysis.

Photoredox-Catalyzed 1,4-Peroxidation–Sulfonylation of Enynones: A Three-Component Radical Coupling Approach for the Synthesis of Highly Functionalized Allenes [PDF]
An Eosin Y-catalyzed visible light-promoted 1,4-peroxidation–sulfonylation of enynones was achieved to give tetrasubstituted allenes. The photoredox catalysis of Eosin Y allowed the concomitant formation of peroxy and sulfonyl radicals, where the ...

Deal;Photoredox Catalysis for the Cycloaddition Reactions
ChemCatChem, 2020 AbstractCycloaddition reaction is a powerful tool for the synthesis of cyclic structures in a green way. High‐energy ultraviolet (UV) light was strictly required for the traditional photochemical processes. However, in the past ten years, discovery of photoredox catalysis for the cycloaddition reactions have attracted significant attention.
