Absolute rate constants have been measured for the reactions of trichloromethylperoxyl radicals with cyclohexane, cyclohexene, and hexamethylbenzene. The CClsO, radicals were produced by pulse radiolysis of air-saturated CCl, solutions containing various amounts of the hydrocarbons. The rate constan

โฆ Synopsis
Saturated hydrocarbon radicals in the hybrid orbital all-valence-electron basis Possess a nonbonding molecular orbital whose eigencoefficients can be written by inspection.
Perturbational MO calculations using these coefficients lead to good correlations of hydrogen abstraction reactivity data.
Fukui and coworkers have developed a valence-electron Hiickel-type molecular orbital treatment of saturated organic molecules and radicals.
