Selective Electrochemical sp3 CO Bond Hydrogenolysis: From Model Compounds to Lignin
ChemElectroChem, Volume 13, Issue 6, 17 March 2026.Electrochemical sp3 CO bond cleavage is systematically investigated under constant‐current conditions using simple aryl ether models and extended to organosolv lignin. Controlled electron flow, regulated proton availability, and a sacrificial magnesium anode enable selective lignin depolymerization, yielding chemically distinct fractions with aromatic
