Haohong Duan IssueVolume: 2021-02-08 Abstract: Oxidative cleavage of C(OH)‐C bonds to afford carboxylates is of significant importance for petrochemical industry and biomass valorization. Here we report an efficient electrochemical strategy for selective upgrading of lignin derivatives into carboxylates by a manganese‐doped cobalt oxyhydroxide (MnCoOOH) catalyst. A wide range of lignin‐derived substrates with C(OH)‐C or C(O)‐C units undergo efficient cleavage to corresponding carboxylates in excellent yields (80‐99%) and operational stability (200 h). Detailed investigations reveal a tandem oxidation mechanism that base from electrolyte promotes the transformation of secondary alcohols and their derived ketones to reactive nucleophiles,。
