ABSTRACT
A mild and efficient method for lignin ß-O-4 cleavage and functionalization was achieved via photocatalysis. This protocol exhibits a broad scope of lignin models and excellent compatibility of functionalization reagents, constructing a series of functionalized lignin-based aromatic compounds. Highly selective formation of alkyl radical species through a proton-coupled electron transfer and ß-scission process provides the opportunity to form new C-C and C-N bonds by reaction with electrophilic reagents.
