The electrochemical fluorination of α-cyclohexenyl-substituted carboxylic esters afforded both perfluoro (9-alkyl-7-oxa-bicyclononane)s and perfluoro(8-alkoxy-9-alkyl-7-oxabicyclononane)s in fairly good yields.As the driving force for the ring-closure in this fluorination, a mechanism which involves a resonance stabilized intermediate radical is proposed. Perfluoro(8-chloro-8-methoxy-9-ethyl-7-oxabicyclononane) and perfluoro(8,8-dichloro-9-ethyl-7-oxabicyclononane) were obtained by the controlled chlorination of perfluoro(8-methoxy-9-ethyl-7-oxabicyclo nonane) with anhydrous aluminum chloride in low yields.Some new fused perfluorobicyclic ethers and a perfluoroacid fluoride obtained in this experiment have been characterized by infrared, mass and 19F nmr spectra and elemental analysis.
