Abstract
The electrochemical oxidation of substituted catechol derivatives has been investigated in the presence of pyrazol-5-ones as C-H acid nucleophiles by using constant current technique in acetate buffer solution. The results indicate that different reaction mechanisms are involved and not only 1,4-Michael adducts but also 1,6-Michael adducts are formed, depending on the nature of the starting catechols and the nucleophiles, as well as the reaction conditions.
