Photoredox Catalysis Using Heterogenized Iridium Complexes** [PDF]

open access: yesChemistry – A European Journal, 2021
Abstract Heterogenized photoredox catalysts provide a path for sustainable chemical synthesis using highly tunable, reusable constructs. Here, heterogenized iridium complexes as photoredox catalysts were assembled via covalent attachment to metal oxide surfaces (ITO, ZrO 2 ,

Molecular Rubies in Photoredox Catalysis

open access: yesFrontiers in Chemistry, 2022
The molecular ruby [Cr(tpe)2]3+ and the tris(bipyridine) chromium(III) complex [Cr(dmcbpy)3]3+ as well as the tris(bipyrazine)ruthenium(II) complex [Ru(bpz)3]2+ were employed in the visible light-induced radical cation [4+2] cycloaddition (tpe = 1,1,1 ...

Asymmetric counteranion-directed photoredox catalysis [PDF]

open access: yesScience, 2023
Photoredox catalysis enables distinctive and broadly applicable chemical reactions, but controlling their selectivity has proven to be difficult. The pursuit of enantioselectivity is a particularly daunting challenge, arguably because of the high energy of the activated radical (ion) intermediates, and previous approaches have invariably required ...

Aromatic Chlorosulfonylation by Photoredox Catalysis [PDF]

open access: yesChemSusChem, 2016
AbstractVisible‐light photoredox catalysis enables the efficient synthesis of arenesulfonyl chlorides from anilines. The new protocol involves the convenient in situ preparation of arenediazonium salts (from anilines) and the reactive gases SO2 and HCl (from aqueous SOCl2).

Photoredox Catalysis for Polymerization Reactions

open access: yesCHIMIA, 2012
Photoredox catalysis is now well-known in organic synthesis for the formation of free radicals under very soft irradiations conditions (e.g. sunlight, household fluorescence or LED bulbs, Xe lamp).
