The reactions between bis(trifluoromethyl)nitroxyl and CF3PX2 (whereX = F, Cl, Br and CN) in 2:1 molar ratio give addition products, [(CF3)2NO]2P(CF3)X2. The bromo and cyano products are unstable. The former decomposes at room temperature to give bromine and perfluoro-2-azapropene, and the latter yields predominantly (CF3)2NOCF3. With CF3PI2, iodine displacement occurs to afford [(CF3)2NO]2PCF3. On

trifluorovinyl ether, and pentafluoropropionyl fluoride. Pyrolysis of perfluoro-(NN-dimethylvinylamine) or of trifluoromethyltrifluorovinylether gives perfluoro-2-azapent-2-ene (55%) and pentafluoropropionyl fluoride (67%), respectively. The rearrangement of the vinylamine probably occurs by two mechanisms (mainly intramolecular and partly radical), since pyrolysis with a large excess of toluene gives
