Homolysis of Substituted Anisoles: Substituent Effects on Phenoxyl Radical Stabilities

  • Stephen E. Stein

Part of the Basic Life Sciences book series (BLSC, volume 49)


The effect of a substituent on reaction thermodynamics (energetics) is perhaps the most fundamental of the “substituent effects.” In free radical reactions, other factors, most notably “polar effects,” are typically deduced from deviations in thermodynamic/rate correlations. A detailed understanding of radical substituent effects therefore requires the availability of thermodynamic information.
