How single and bifurcated hydrogen bonds influence proton-migration rate constants, redox, and electronic properties of phenoxyl radicals.
Hydrogen-bonded phenoxyl radicals are made and the strength of the hydrogen bond between the O(phenoxyl) and the H(ammonium) atoms strongly affects their stability. The rate consts. for the intramol. proton-migration process in these systems are reported and a bifurcated hydrogen-bonded system has been characterized. Investigations show that the proton transfer from the phenoxyl-radical cation to the tertiary amine is assisted by a neighboring nitrogen atom. [on SciFinder(R)]
