Perfluorocarbon Epoxides, Part 1
Abstract
Potential ester solvents were prepared, tested for stability toward fluoride ion, and used as solvents in *(HFPO) oligomerizations. These materials were found to be inferior to the conventional glyme solvents in HFPO oligomerizations. Studies directed toward the preperation of a 2.3 spiroepoxide were culminated by the synthesis of perfluoro(1-oxaspiro(2.3)hexane). Considerable effort was spent on obtaining perfluorocyclobutanone, an essential intermediate in the spiroepoxide synthesis. Attempted polymerization and reaction of the spiroepoxide are discussed. A new class of compound, a perfluorinated ether epoxide, was prepared by the oxidation of the vinyl ether derived from HFPO trimer. Of the three reagents tested for this oxidation (O2, H2O2/Na2CO3, OF2/O2) the OF2 catalyzed oxidation seemed best. Attempts to extend this reaction to the simplest homolog of this class of epoxide are discussed. Several approaches leading to the preperation of perfluorinated-N-alkyl azitidines were investigated.
