Abstract : Part of the objective of this program is the preparation or attempted preparation of new fluorine containing chemical species by the Simon's electrochemical process. The results of numerous operations in a variety of cells are summarized. Studies have been made with some of the resulting materials in order to find unique reactions of these materials and thereby new compounds exhibiting the chemical and thermal stability associated with fluorocarbons. The preparation, pyrolysis or thermal reactions of certain simple fluorocarbon sulfides with fluorocarbon olefins are described. The sulphides are CF3SF5, C2F5SF5, (CF3)2SF4 and (C2F5)2SF4. The olefins involved were CF3CF=CF2, and CF3N=CF2. The synthesis and properties of fluorocarbon derivatives having hetero atoms such as oxygen or nitrogen in the principal carbon chain of the molecule have been studied. It has been shown that a perfluoro compound having an alternating chain C-O-C-N-C cannot be synthesized directly from the organic analogue. When prepared indirectly, however, such a chain is chemically and thermally stable. The compounds (CF3)2NCOF, CF3N=CF2, and (CF3)2NCF2COOH, which are the N-hetero analogues respectively of (CF3)2CFCOF, CF3CFCF2, and (CF3)2CFCF2COOH, are discussed.
