Developing highly efficient catalyst systems to transform lignin biomass into value-added chem. feedstocks is imperative for using lignin as renewable alternatives to fossil fuels. Recently, the pre-activated strategy involving the selective oxidation of Cα alc. of lignin substrates containing (β-O-4) linkage mode significantly increases the depolymerization efficiency of native aspen lignin from 10-20 to 60 weight-%. the authors reported the synthesis of a dinuclear oxovanadium complex 2 that is capable of selectively oxidizing the Cα alc. (80-100% selectivity) of various dimeric lignin substrates under a mild condition. Further study of catalytic mechanism revealed that two V=O motifs of complex 2 could serve as proton abstraction sites for both Cα and Cγ alc. of dimeric lignin substrates, resp. The dinuclear vanadium intermediate 4 demonstrates the ability to uptake two electrons resulting from the oxidation of Cα alc. and yields two corresponding mononuclear VIV intermediate 5. The mononuclear VIV intermediate 5 exhibits a characteristic 8-line EPR spectrum and possesses one unpaired electron determined by the Evans method. The established structure-reactivity relations will be able to shed light on the future directions for rational design of highly efficient catalysts for selective oxidation of lignin biomass.
