    摘要: A perfluoroalkyl halogenide represented by the formula: ##STR1## wherein X stands for one element selected from the group consisting of iodine and bromine, R.sub.f for a perfluorohydrocarbon group, n for an integer in the range of 1 to 3, and m for an integer in the range of 1 to 3, provided that n and m satisfy the relationship, n.gtoreq.m, is produced by a method which consists essentially in subjecting a perfluorocarboxylic acid fluoride represented by the formula, ##STR2## wherein R.sub.f and n have the same meanings as defined above, to a thermal reaction with a lithium halogenide represented by XI, wherein X has the same meaning as defined above.

    摘要: Perfluorocarboxylic acid fluorides represented by the formula A-B, wherein A is either ##STR1## and B stands for a perfluoro-di-substituted amino group, and perfluoro(dialkylaminopropenes) represented by the formula A"-B", wherein A" stands for ##STR2## and B" has the same meaning as B defined above, are novel compounds. Methods for the production of these novel compounds are also disclosed.
