摘要

4-(Dimethylamino) pyridine (DMAP) and 4-pyrrolidinopyridine (PPY) are known to catalyze the acylation of alcohols with acid anhydrides and to increase the rate of acylation by a factor of lo4.'Recently, Vedejs et al. reported tributylphosphine as a similar catalyst for the acylation of alcohols.* Although the mechanism of tributylphosphine catalysis is not yet the remarkable catalytic activity of these basic and nucleophilic catalysts can be interpreted by ...
