Abstract
Abstract: Evaluation of the stabilization energy of the nonatetraenyl radical directly from the enthalpy of activation of the thermal anti-syn rearrangement of a semirigid nonaene having a symmetrical distribution (4-1-4) of double bonds is thwarted by insolubility. Indirect comparison of the enthalpy of activation of an unsymmetrical (4-1-2) heptaene with that of an already determined symmetrical (2-1-2) pentaene leads to an inferred enthalpy of ...
