Abstrakt: 1.The reactivities of a series of anhydrides of alkane, fluoroalkane, and perfluoroalkane carboxylic acids were determined using the method of competing acylation-cyclodehydration and the cyclization process was shown to be subject to polar and steric effects of the groups at the reaction centers of the anhydrides.2.Carboxylic acid anhydrides react with perfluorocarboxylic acids with the formation of the mixed anhydride and the corresponding carboxylic acid.
