Description:
A method is described for determining heats of heterolysis, DeltaH(het), from the heats of reaction of resonancestabilized carbenium ions with carbanions in solution. These results can be converted into heats of homolysis, DeltaH(homo), for the same bonds by combining DeltaH(het) values with electron transfer energies, deltaG(ET) (deltaG(ET) approximately deltaH(ET)), obtained from redox potentials of the reacting ions. The results provide a comprehensive tabulation of DeltaH(het), DeltaH(homo), and DeltaG(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.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arnett, E M -- Amarnath, K -- Harvey, N G -- Cheng, J P -- New York, N.Y. -- Science. 1990 Jan 26;247(4941):423-30.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17788608" target="_blank"〉PubMed〈/a〉
