Recalculations of enthalpies using a different energy minimization scheme (pattern search method) 8 and taking the conformational flexibility of the bicyclo [2.2. 2] octane skeleton8 into account give essentially the same results as shown above. Comparison between experlmental (Table IV) and calculated enthalpies revealed that our calculations overestimated the enthalpy of bicyclo [2.2. 2] octene and underestimated those of bicyclo [ ...
