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 perfluoro1-oxaspiro2.3hexane. 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, H2O2Na2CO3, OF2O2 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.
