摘要：
Ionic liquid 1-benzyl-3-methylimidazolium bis(trifluoromethylsulfonyl)-imide ([BnMIm][NTf2]) can promote the generation of the (OOH)-O-center dot free radical and thereby efficiently transformed the beta-O-4 lignin model compound 2-phenoxyacetophenone into benzoic acid and phenol using O-2 as the oxidant. Furthermore, the IL-based metal-free catalytic system can also depolymerize other lignin model compounds and organosolv lignin effectively.
