Radical decomposition reactions: factors affecting transition-state energetics and geometries

Abstract

The enthalpies, activation energies, and geometries of transition states of the decomposition of organic radicals, viz., alkyl, alkoxyl, acyl, peroxyl, etc., are reviewed. The results of semiempirical and quantum chemical calculations are compared with experimental data. Special attention is given to an analysis of physicochemical factors affecting the activation barriers and geometry of transition states of radical decomposition.
