Kinetics of iodination of 6-substituted 2-acetonaphthones and of 4-substituted 1-acetonaphthones in 20percent pyridine-20percent methanol-60percent water (v/v) have been followed at three temperatures.The Hammett equation applies very well to these reactions.The rate constants for various heterocyclic base-catalysed iodination of acetophenone and of 1- and 2-acetonaphthones in 60percent (v/v) methanol-water solvent have been correlated with pKa values of the conjugate acids of the heterocyclic bases via the Broensted equation giving β values of 0.88, 1.01 and 0.92 for acetophenone, 1-acetonaphthone and 2-acetonaphthone respectively.The influence of solvent on the rates of pyridine-catalysed iodination of acetophenone and of 1- and 2-acetonaphthones has also been studied.
