Reactivity of Superoxide Ion with Organohalogens and Chalcones
The cathodically in situ generated superoxide anion radical a proven bioactive species is a multipotent reagent. As an effective nucleophile it reacts with organohalogens in an addition-elimination process to afford the corresponding phenols. The cleavage of chalcones (enones) to carboxylic acid(s) occurs in a facile step with superoxide mediated (O2- /O2) reaction. The reactivity of superoxide anion radical with chalcones in the presence of henzoyl chloride as an affector is different and leads to radical dimer products. The plausible mechanisms have been proposed for the above reactions on the basis of product identification and cyclic voltammetric studies.
