Efforts to synthesize SF4CFNOCF2Cl and to polymerize C2H5SNO are described. Several fluoroaromatic monomers and precursors have been prepared including 1,4-dibromotetrafluorobenzene, tetrafluoroterephthalic acid, monosilver tetrafluoroterephthalate, tetrafluoroterephthalyl mononitrite and 1, 4-diaminotetrafluorobenzene. Continued efforts to prepare SF5COOH and to synthesize SF5CF2COOH are described. Low temperature polymerization of thiocarbonyl fluoride with CF3No, CF2CF2, and CF3NOCF2CF2 using a triethylboraneoxygen catalyst has been examined. Trifluoronitrosomethane and tetrafluoroethylene were polymerized with a coordination catalyst. The reactivity of CF3SCFNOCF2Cl is apparently low compared with CF3NO since little, if any, of this compound polymerized in the system CF3NOCF2CF2 CF3SCFNOCF2Cl. An attempt to prepare C2H5SNO and polymerize it with CF2-CF2 in situ was not successful.
