Abstract

The dehydration of amic acids, derived from the reaction of cyclic anhydrides with primary amines, to yield imides is a general method for the preparation of this important class of heterocyclic compounds and is of major commercial significance in the conversion of polyamic acids to polyimides.'In principle, the thermal ring closure of amic
