Conclusions
-
1.
The polar effect of substituents during the acylation of phenols with benzoyl chloride in the presence of a strong tertiary amine corresponds to a scheme involving general base catalysis.
-
2.
In the case of the relatively weak tertiary amine a shift in the reaction mechanism probably occurs on passing from the more acidic to the less acidic phenols: general base catalysis gives way to nucleophilic catalysis.
