Epimerization of 2,4-dibenzilidene-6-methylbicyclo(3.1.0)hexane-3-one
摘要:
Thermal epimerization of the title compound occurs readily at > 150-degrees-C, with Eyring parameters of DELTA-H double-ended dagger = 29.8 kcal/mol and DELTA-S double-ended dagger = -10.8 cal/mol-K, consistent with a planarized intermediate or transition state.
