Abstract
The conversion of lignin into high–value-added chemicals represents a promising strategy to enhance its valorization. However, developing catalytic systems and reagents that enable the selective activation and functionalization of specific linkages within its complex polymeric structure remains highly challenging. Here, we report a photocatalytic method for the efficient cleavage and gem -difluoroalkenylation of β-O-4 and β-1 lignin models, as well as native lignin biomass. By using α-trifluoromethyl alkenes as functionalization reage
