The initial rates of reaction of a number of para- and meta-substituted toluenes with chromyl chloride in carbon tetrachloride solution have been measured and the results analyzed using Hammett's relation. The results are interpreted in terms of electrophilic attack by CrO2Cl2 molecules. The reaction appears to be marked by an unusually large effect of ring substitution on the entropy of activation. The mechanistic significance of this observation is discussed.
