Reduction of acetone and its hydrocoupling with acrylonitrile in aqueous sulphuric acid solution at a mercury cathode

Abstract

The mechanism of the reduction of acetone and its hydrocoupling with acrylonitrile in aqueous sulphuric acid at a mercury cathode has been investigated using steady and non-steady state controlled potential techniques under experimental conditions employed in synthesis. The results indicate that a primary electron transfer occurs to an adsorbed acetone molecule, with protonat ion, yielding an adsorbed radical which is the common precursor of the diverse products of acetone reduction alone and of the coupled products obtained in the presence of acrylonitrile.
