A process for the preparation of perfluorinated heterocyclic compounds of the general formulas Ia and Ib wherein m means 3 or 4 and X represents a -CF₂-O-CF₂ group, a -CF₂-CF₂-CF₂ group or a -CF (CF₃) -CF₂ group, and their mixtures and the perfluoro-N-cyclohexylmorpholine produced by the process. The compounds are obtained by electrochemical perfluorination starting from corresponding cycloalkenyl derivatives and can be used, inter alia, for the preparation of medically usable aqueous emulsions such as blood substitutes. |
