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.

prepared in 32–96% yield by the reaction of olefins with ethylidene iodide and diethylzinc. The reaction is electrophilic, and proceeds stereospecifically. In the case of the reaction with 1,2-disubstituted olefins, cis and transolefins affords cyclopropane derivatives whose configurations with respect to the substituents from original olefins are cis and trans, respectively.
