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 ...

Organic synthesis using photoredox catalysis [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2014
Natural photosynthesis is a remarkable chemical machinery that enables our life on earth and delivers a constant stream of oxygen and organic biomass. We should acknowledge this fact with humbleness, especially because we have not been able yet to mimic this process in a reliable way even after decades of intense research.

Cooperative Photoredox Catalysis Under Confinement. [PDF]

open access: yesChemistry
AbstractPhotoredox catalysis has emerged as a potent means to conduct synthetic chemistry. Leveraging light to achieve challenging organic transformations has led to many developments, both of fundamental and industrial nature. Despite their potency, photoredox processes are inherently diffusion controlled, which can limit their ability to enable both ...

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).

Excited Organic Radicals in Photoredox Catalysis. [PDF]

open access: yesJACS Au
Many important synthetic-oriented works have proposed excited organic radicals as photoactive species, yet mechanistic studies raised doubts about whether they can truly function as photocatalysts. This skepticism originates from the formation of (photo)redox-active degradation products and the picosecond decay of electronically excited radicals, which

Interfacial Charge Transfer Regulates Photoredox Catalysis. [PDF]

open access: yesACS Cent Sci
Photoredox catalytic processes offer the potential for precise chemical reactions using light and materials. The central determinant is identified as interfacial charge transfer, which simultaneously engenders distinctive behavior in the overall reaction.
