The reactions of elemental fluorine with structually crowded hydrocarbon ethers and amines have been studied.The perfluorinated products are currently of interest in biomedical or electronic industrial applications.The syntheses by direct fluorination of perfluoro(tert-butyl methyl ether), perfluoro(tert-butyl isobutyl ether), perfluoro(1,2-di-tert-butoxyethane), perfluoro(cyclohexyl neopentyl ether), perfluoro(2,2,5,5-tetramethyltetrahydrofuran), perfluoro(2,5-dimethyltetrahydrofuran), bis(perfluoroisopropyl) ether, perfluoro(2-ethyltetrahydrofuran), and perfluoro(1,2,2,6,6-pentamethylpiperidine) are reported.The skeletally rearranged byproducts perfluoro(isobutyl methyl ether), perfluoro(2,2,5-trimethyltetrahydrofuran), perfluoro(2,2,5-trimethyltetrahydropyran), 3-hydropentadecafluoro-2,2,5,5-tetramethyltetrahydrofuran, perfluoro(isopropyl propylether), and perfluoro(ethyl isopropyl ether) were also characterized.The 19F and 13C (19F decoupled) NMR assignments of these perfluorinated chemicals are discussed.
