Abstract The title perfluoro-α-lactam (1) was found to react with N, N-dimethylformamide to give initially a betaine (2) which undergoes ring enlargement to produce the isomeric 2- dimethylamino-3, 4, 4-tri (perfluoroalkyl) substituted 5-oxazolidone (3). Related betaines were also obtained on reaction of 1 with pyridine, quinoline, benzalaniline, and p- dimethylaminobenzaldehyde.
