ABSTRACT:
A perfluoro-cyclic imine represented by the formula: ##STR1## is produced by a method which comprises placing in a reaction vessel a perfluoro compound represented by the formula: ##STR2## wherein X stands for one member selected from among CF.sub.2, CF(CF.sub.3), and oxygen atom, M for one member selected from among monovalent alkali metal ions and alkaline earth metal ions, and n for 0, 1, or 2 and heating the perfluoro compound to a temperature in the approximate range of 100.degree. C. to 500.degree. C.
