The kinetics of oxidation of chalcones by quinaldinium fluorochromate has been studied in aqueous acetic acid medium in the presence of perchloric acid. The order of the reaction is found to be one with respect to oxidant and hydrogen ion. The order with respect to substrate is found to be fractional. The reaction rates have been determined at different temperatures and the activation parameters calculated. Electron withdrawing substituents are found to enhance the rate of the reaction and electron releasing substituents are found to retard the rate of the reaction and the rate data obeys the Hammett relationship. From the observed kinetic results a probable mechanism has been proposed.
