Reactions of Alkyl Radicals with Nitrogen Trifluoride

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.
