Interfacial Anion-Induced Dispersion of Active Species for Efficient Electrochemical Baeyer-Villiger Oxidation.

ABSTRACT: Degradable polymers are an effective solution for white plastic pollution. Polycaprolactone is a type of degradable plastic with desirable mechanical and biocompatible properties, and its monomer, ε-caprolactone (ε-CL), is often synthesized by Baeyer-Villiger (B-V) oxidation that demands peroxyacids with low safety and low atom-efficiency. Herein, we devised an electrochemical B-V oxidation system simply driven by H₂O₂ for the efficient production of ε-CL. This system involves two steps with the direct oxidation of H₂O₂ into •OOH radicals at the electrode surface and the indirect oxidation of cyclohexanone by the generated reactive oxygen species. The modulation of the interfacial ionic environment by amphipathic sulfonimide anions [e.g., bis(tri
