Abstract | The rate constants for isomerization of 2-aryl-2-methylpropyl-1 to 1-aryl-2-methylpropyl-2 radicals have been measured by EPR spectroscopy over a range of temperatures. The radicals were derived by hydrogen abstraction from the following compounds: tert-butylbenzene, 1,3-di-tert-butylbenzene, 4-tert-butylpyridine, 2,6-di-tert-butylpyridine, and 2-tert-butylnaphthalene. The rates of isomerization of the radicals derived from the two pyridines and the naphthalene are significantly faster than the rates of isomerization of the radicals from the two benzenes. |
