Preparation of a series of substituted fluoromethylnaphthalenes
A series of 22 3- and 4-substituted 1-fluoromethylnaphthalenes have been synthesized.Details of practical procedures for the preparation of all intermediates are described, and physical properties for all of the substituted naphthalenes synthesized, and spectral parameters for 51 previously unknown compounds, are given.

Kinetics of Base-catalysed Iodination of Substituted Acetonaphthones
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.
