Interaction of 1-tert-perfluorobutyl-3,3-di(perfluoromethyl)-2-aziridinone with weak nucleophiles

Article abstract of DOI:10.1007/BF00697089

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.
