Rates of enantiomerization of trans-1,2-disubstituted cyclopropanes correlate with substituent radical stabilization energies
Abstract
Experimental ΔG‡(enantiomerization) values for trans-1,2-disubstituted cyclopropanes correlate in strict linearity with the sum of substituent radical stabilization energy terms; the two ends of the 1,3-disubstituted trimethylene diradicals implicated in these thermal enantiomerization reactions appear to be thermochemically independent.
