155ChemInform Abstract A novel method for the preparation of the title compound (II) is described, which employs aqueous NaOCl in the presence of MeCN for the epoxidation of perfluorocyclohexene (I) to give (II) in high yield. The reaction of (II) with alkali fluorides yields the perfluorocyclohexanone (III) along with a mixture of oligomers, from which the dimer (IV) can be isolated. The product ratio (III)/(IV) depends strongly on the polarity of the solvent employed. The reaction of (II) with electrophiles such as SbF5 or FSO3H proceeds only at high temperatures to yield the cyclohexanone derivatives (III) or (VI). Reduction of (II) by LiAlH4 affords the nonafluorocyclohexanol (V).
