The purpose of this project is to conduct the necessary research for the preparation of unsaturated organic compounds containing fluorine and, when synthetic methods have been developed, to prepare various fluoro-olefins which may give elastomers which are oil and fuel resistant and which retain their elasticity at low temperatures. CF2CH-CF2NO and CF2CF-CF2NO have been prepared in 24.5 and 34 yield respectively by reacting the corresponding polyfluoroallyl iodide with nitric oxide in the presence of mercury. Polyfluoroallyl chlorides and iodides react with nitrogen dioxide in the presence of mercury to give high yields of the corresponding polyfluoroacrylic acid fluorides.
