Comparison of a series of laccase mediators in the electro-oxidation reactions of non-phenolic lignin model compounds

- Electro-oxidation of non-phenolic lignin model compounds were investigated.
- NHPI mediated electro-oxidation gave the corresponding CαO product in high yield.
- The oxidation with HBT, VLT, TEMPO gave a CαO product in low yield.
- ABTS-mediated electro-oxidation gave a Cα-Cβ cleavage product in low yield
- NHPI was the best mediator for selective Cα-carbonylation among the laccase mediators.
