Lignin is a high molecular weight macromolecule prepared by plants via radical reactions of methoxylated phenylpropanoid alcohols such as syringyl alcohol. While many lignin C-O bonds can be cleaved by simple alkaline heat treatment, cleavage of C-C bonds is more problematic. In collaboration with CENTC[1] and Lignoworks[2] we are investigating base metal catalysts (V, Cu, Mn) for selective aerobic C-C bond cleavage of lignin models and extracts.[3] Issues associated with catalyst lifetime and water tolerance will be addressed.
