Abstract
For the oxidation of para- and meta-substituted benzaldehydes by nicotinium electron releasing substituents retard and the electron withdrawing substituents enhance the rate of the reaction; from the kinetic data obtained activation parameters have been computed and a plausible mechanism has been proposed.
