Abstract
From the heat of hydrogenation of 5, the activation enthalpy for the r acemization of the title compound, and the oxygen dependance of the tr apping rate of the intermediate diradical 8 the energy profile for the degenerate methylene-cyclopropane rearrangement can be constructed, w hich leads to heats of formation for the triplet and singlet state of the diradical 8 of Delta H-f(0) . 93.9 and 95.6 kcal mol(-1), respecti vely.
