Abstract:
From the heat of hydrogenation of title compd. I, the activation enthalpy for the racemization of I, and the oxygen dependence of the trapping rate of the intermediate diradical II, the energy profile for the degenerate methylenecyclopropane rearrangement can be constructed, which leads to heats of formation for the triplet and singlet state of II of 93.9 and 95.6 kcal mol-1, resp.
