Comprehensive Summary A one‐pot transformation of aliphatic and aromatic tertiary amines to novel fluorinated enaminones has been developed, utilizing perfluoroalkyl ether carboxylates (PFECA salts) featuring “–CF 2 O–” units as the fluorine‐containing reagents. Carbonyl fluoride, acyl fluorides anhydrides by thermal decomposition these PFECA salts were proposed act key active species that trigger tandem oxidation–acylation process amines, through enamine intermediates.
