The gas-phase acidities of chloroanilino-radicals have been measured, and have been combined with the electron affinities of chlorophenylnitrenes to determine the N-H bond dissociation energy of chloroanilino-radicals and the enthalpies of formation for the triplet, singlet, and radical anion states of the isomeric nitrenes. There is little difference found between the bond dissociation energies in the radicals and those in the corresponding anilines, indicating little interaction between the unpaired electrons in the chlorophenylnitrene, as expected. The values obtained are in good agreement with the values obtained from the theoretical calculations. [GRAPHICS] (C) 2014 Elsevier Ltd. All rights reserved.
