The kinetics of reaction between benzyl chloride and phenol (or substituted phenols) in the presence of sodium hydroxide have been investigated. A differential application of the effect of substituents on the reaction rate to distinguish between a rate-limiting oxygen or carbon attack has been attempted. Considerable scatter in the Hammett plot for the latter attack points to an essentially O-alkylation. The rate constants correlate well with pKa values of the different phenols. The influence of salt and solvent on the reaction rate suggests this reaction to be an ion-dipole one.

The kinetics of chlorination of 2,3 and 4-aoetyl-pyridines by N-chlorosaccharin have been studied in aqueous acetic acid medium both in the absence and in the presence of sulphuric acid. The solvent effect on these reactions has also been studied. The results have been rationalised on the basis of a suitable mechanism.
