Process for converting perfluorinated esters to perfluorinated acyl fluorides and/or ketones
 A process for converting perfluorinated carboxylic acid esters to perfluorinated acyl fluorides and/or perfluorinated ketones comprises the step of combining at least one perfluorinated carboxylic acid ester with at least one initiating reagent selected from the group consisting of gaseous, non-hydroxylic nucleophiles; liquid, non-hydroxylic nucleophiles; and mixtures of at least one non-hydroxylic nucleophile (gaseous, liquid, or solid) and at least one solvent which is inert to acylating agents. The process enables the dissociation of even high molecular weight, perfluorinated esters.
