Abstract

The anodic oxidation in methanol of some lignin model compounds, the C17–C18 compounds ((1)–(5), has been studied to ascertain factors influencing cleavage of Cα Cβ bonds cf. substitution. Cyclic voltammetric oxidation peak potentials were influenced by structure but not by pH. Preparative-scale electrolyses gave 3, 4-dimethoxybenzaldehyde as the major product from compounds (1)–(3), corresponding to cleavage of th Cα Cβ ...
