Abstract:
Photolysis of mixtures of nitrogen trifluoride with the appropriate ketones (in the temperature range 303–486 K) has enabled the reactions of CH3, CF3, C2H5, i-C3H7 and t-C4H9 radicals with nitrogen trifluoride to be studied. With the smaller radicals only the abstraction of difluoroamino radicals is important, but with i-C3H7 and t-butyl both difluoroamino and fluorine abstraction occur. The Arrhenius parameters are given. The disproportionation—combination ratio for methyl and t-butyl radicals was found to be 0.83 ± 0.02.
