A Roadmap Towards Visible Light Mediated Electron Transfer Chemistry with Iridium(III) Complexes

Free Radical Chemistry Enabled by Visible Light-Induced Electron Transfer

Harnessing visible light as the driving force for chemical transformations generally offers a more environmentally friendly alternative compared with classical synthetic methodology. The transition metal-based photocatalysts commonly employed in photoredox catalysis absorb efficiently in the visible spectrum, unlike most organic substrates, allowing for orthogonal excitation. The subsequent exc...

The Electron Transfer Chemistry of Nitrosyl Complexes

Visible-Light-Induced Click Chemistry.

A rapid and catalyst-free cycloaddition system for visible-light-induced click chemistry is reported. A readily accessible photoreactive 2H-azirine moiety was designed to absorb light at wavelengths above 400 nm. Irradiation with low-energy light sources thus enables efficient small-molecule synthesis with a diverse range of multiple-bond-containing compounds. Moreover, in order to demonstrate ...

A visible-light-driven transfer hydrogenation on CdS nanoparticles combined with iridium complexes.

A visible-light-driven transfer hydrogenation of carbonyl and C=C compounds has been developed by coupling CdS nanoparticles with iridium complexes, exhibiting high activities, excellent selectivities and a unique pH-dependent catalytic activity.

Light Induced Electron Transfer Reactions of Metal Complexes

Properties of the excited states of tris(2,2'—bipyridine) and tris(l,lO—phenanthroline) complexes of chromium(III), iron(II), ruthenium(II), osmium(II), rhodium(III), and iridium(III) are described. The electron transfer reactions of the ground and excited states are discussed and interpreted in terms of the driving force for the reaction and the distortions of the excited states relative to th...
