Photoredox-Catalyzed Intermolecular Radical Addition to Allenamides: A Complementary Approach to Conjugated N-Acyliminium Formation. [PDF]
, 2019 An intermolecular radical addition, using photoredox catalysis, to allenamides is reported. This transformation synthesizes N-acyl-N’-aryl-N,N’-allylaminals, and proceeds by a conjugated N-acyliminium intermediate, that previously, has only been ...

Conversion of Lignin Models by Photoredox Catalysis
ChemSusChem, 2018 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 ...
