disubstituted ones. Controlled-potential oxidation at the glassy carbon anodes and in a neutral LiClO4−methanol medium led to more complex mixtures of products, namely, polymers and new coupling productsfrom monosubstituted substrates and quinones and side-chain oxidation (or substitution) productsfrom the disubstituted ones. Three new coupling products were isolated and characterized by X-ray measurements

The reaction of 2-methoxy-1,4-benzoquinone with methoxyphenolic derivative compounds obtained from wood tar constituents, assisted by palladium (II) acetate in acetic acid, allowed the preparation of five novel methoxyaryl-substituted 1,4-benzoquinones, as well as four structural isomer mixtures.
