Visible-Light-Promoted C–S Cross-Coupling via Intermolecular Charge Transfer

Garret Miyake presents a visible-light-promoted C–S cross-coupling to access aryl thioethers.

The development of synthetic methods based on harnessing the power of visible light for promoting stereoselective reactions using photoredox catalysts is at the forefront of modern organic chemistry. The group of Professor Garret Miyake at Colorado State University (Fort Collins, USA) and University of Colorado Boulder (USA) has been working toward developing strongly reducing organic photoredox catalysts that operate using visible light, in particular for organocatalyzed atom-transfer radical polymerization.

They have shown that N,N-diaryl dihydrophenazines or N-arylphenoxazines are successful photoredox catalysts for the synthesis of polymers with controlled molecular weights and architectures and were interested to apply those molecules in other transformation such as C–S cross-coupling reactions as described in this article.
