Abstract
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.
