摘要：

A method is described for determining heats of heterolysis, ΔH het, from the heats of reaction of resonance-stabilized carbenium ions with carbanions in solution. These results can be converted into heats of homolysis, ΔHhomo, for the same bonds by combining ΔHhet values with electron transfer energies, ΔG ET (ΔGET ≈ ΔHET), obtained from redox potentials of the reacting ions. The results provide a comprehensive tabulation of ΔHhet, ΔHhomo, and ΔG ET values for an extended series of organic compounds and are examined in terms of their interrelationships and a number of related properties of the ions and radicals.
