Visible-Light Photoredox Catalyzed Formation of Triarylethylenes Using a Low-Cost Photosensitizer
Visible-light photoredox catalysis using biacetyl (BA) as a low-cost photosensitizer enables the efficient formation of triarylethylenes (TAEs) via a Mizoroki–Heck-type coupling. The reaction proceeds efficiently in acetonitrile upon blue LED irradiation

Conversion of Lignin Models by Photoredox Catalysis
AbstractOne prominent goal of 21st century research is to develop a sustainable carbon‐neutral biorefinery. Lignin is an important component of lignocellulosic biomass; however, it is currently underutilized owing to its highly cross‐linked, complex, and randomly polymerized composition, which poses a significant challenge to its depolymerization and ...
