Esterification of carboxylic acids capable of forming ketene intermediates upon treatment with carbodiimides permits the selectiveacylation of alcohols in the presence of phenols lacking strong electron-withdrawing groups. The selectivity of acylations involving highly acidic phenols could be reversed through the addition of catalytic amount of acid. Esterification of other carboxylic acids was found
