Photoredox-catalyzed C–C bond cleavage of cyclopropanes for the formation of C(sp 3)–heteroatom bonds

Nature Communications, 2022
The development of new methodologies for the construction of C(sp 3)–heteroatom bonds under mild conditions is desirable. Here the authors report the formation of C(sp 3)–heteroatom bonds via ring opening of arylcyclopropanes enabled by photoredox ...

Photoinduced Organocatalyzed Atom Transfer Radical Polymerization (O-ATRP): Precision Polymer Synthesis Using Organic Photoredox Catalysis

Chemical Reviews, 2021
The development of photoinduced organocatalyzed atom transfer radical polymerization (O-ATRP) has received considerable attention since its introduction in 2014. Expanding on many of the advantages of traditional ATRP, O-ATRP allows well-defined polymers

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.

A Dual Cobalt and Photoredox Catalysis for Hydrohalogenation of Alkenes.

Journal of the American Chemical Society
We demonstrate hydrohalogenation of aliphatic alkenes with collidine·HX salts through dual photoredox/cobalt catalysis. The dual catalysis enables conversion of a proton and a halide anion from collidine·HX salt to a nucleophilic hydrogen radical ...

Shedding Light on the Oxidizing Properties of Spin-Flip Excited States in a CrIII Polypyridine Complex and Their Use in Photoredox Catalysis

Journal of the American Chemical Society, 2022
The photoredox activity of well-known RuII complexes stems from metal-to-ligand charge transfer (MLCT) excited states, in which a ligand-based electron can initiate chemical reductions and a metal-centered hole can trigger oxidations. CrIII polypyridines
