Cu-Catalyzed Funneling Oxidation Enables C-C Bond Cleavage in Lignin-derived Compounds.
The structural complexity and chemical heterogeneity of lignin present a formidable barrier to its use as a sustainable replacement for petroleum-derived aromatics. Here, we report a robust, earth-abundant copper/nitroxyl catalytic system that achieves the aerobic oxidative funneling of crude, non-pre-fractionated redu...
