Popis: | 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. |
