Abstract : Methods were studied for the preparation of perfluoroallyl bromide and iodide. The latter olefin reacted with alcohols to produce ethers such as CF3CH2OCF2CF=CF2. The reaction of haloethylenes and haloalkanes in the presence of Lewis acids were studied and variations from the literature were noted. Attempts were made to prepare (CF=CFCH2CH2CH2)2O from the allyl ethers but cyclic ethers were formed. An investigation was initiated of the radical addition of CF3CF2CCl3, CF2CLCF2CCl3, CFClBrCFClBr and CCl3CF2CFClBr with various olefins. Preparation of perfluoroalkane epoxides was investigated.
