Catalytic oxidative conversion of C/G-type lignin coexisting in Tung nutshells to aromatic aldehydes and acids

A catalytic oxidation strategy is reported for the conversion of C/G-lignins coexisting in Tung nutshells to produce aromatic aldehydes and acids. A C/G monomer yield as high as 60.8 mg g −1 (or 12.9 wt%) was achieved by the CuCl 2 /CH 3 CN/H 2 O system.
