Conclusions
-
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.
