RADIOLYSIS OF TETRACHLOROMETHANE

Electron spin resonance studies of tetrachloromethane after exposure to (60)Coγ-rays at 77 K reveal the formation of .CCl3 and CCl4.+ radicals.On warming in the presence of spin-traps, or on irradiating fluid solutions, nitroxide radical adducts have been detected that are characteristic of .CCl3 and chlorine atom adducts.In the light of this evidence and that of other investigators a mechanism for the radiolysis of tetrachloromethane is postulated.In the presence of oxygen, .CCl3 radicals are converted into Cl3COO. radicals.The use of spin-traps to detect these radicals is described and evaluated.

Halogen abstraction reaction between aminoalkyl radicals and alkyl halides: Unusual high rate constants

The very high reactivity of aminoalkyl radicals toward the halogen abstraction reaction is reported for the first time. Reaction rate constants with CCl4 and CBr4 are close to the diffusion limit: they are about 4-5 orders of magnitude higher than those previously determined for typical alkyl radicals. A better understanding of this unusual behavior is obtained using molecular orbitals (MO) calculations. The participation of polar effects is directly evidenced. This approach can be useful for the design of new reducing agents.

Temperature dependence of the reactions of phenyl radicals with 1,1-diphenylethylene, carbon tetrachloride, and cyclohexene

The reaction of phenyl radicals with 1,1-diphenylethylene (DPE), carbon tetrachloride, and cyclohexene has been examined over a range of temperatures using laser flash photolysis techniques. The activation energies are 0.71 ± 0.04, 3.53 ± 0.11 and 2.32 ± 0.33 kcal/mol, and the preexponential factors, expressed as log (A/M-1s-1), are 9.19 ± 0.03, 8.96 ± 0.09, and 9.02 ± 0.26, for DPE, CCl4, and c-C6H10, respectively. In particular the CCl4 data provide a much needed reference for competitive studies.
