Electron spin resonance studies of the radicals formed from C-nitroso compounds and olefins. Part 3.—Reactions of fluoro-olefins with trifluoronitrosomethane and with 2,4,6-tribromonitrosobenzene

Abstract

The free-radical-generating reactions of fluorinated alkenes with trifluoronitrosomethane and with 2,4,6-tribromonitrosobenzene have been investigated. In general, two types of radicals are formed, namely RN(O)CF₂CXYQ and RN(O)CXYCF₂Q, where RNO is the nitroso compound and CF₂CXY the alkene; Q is an unknown group and may be different for each type of radical. The former nitroxides predominate at low temperatures and show a large reduction in concentration above ca. 0 °C. Other workers have examined the reactions of trifluoronitrosomethane with fluorinated alkenes, and their findings are compared with ours.
