ABSTRACT:
Perfluorobicyclolactam compounds represented by the general formula: ##STR1## wherein --A-- stands for ##STR2## l, m, and n respectively stand for 0 or 1, 3 or 4, and 1 or 2, and R.sub.f stands for a lower perfluoroalkyl group, are novel compounds. These compounds are useful as intermediates for the synthesis of, e.g., functional macromolecular membranes and lubricants. These compounds are produced by subjecting compounds of the general formula: ##STR3## and fuming sulfuric acid to a thermal reaction.
