Abstract
The effect of a fluorine substituent on the thermodynamic stability of a cyclopropane ring is not quantitatively well un-derstood at present. Our earlier study of the geometrical isomerization of 1, l-difluoro-2, 3-dimethylcyclopropane indicated that gem-difluoro substituents weaken cyclopropane to cleavage by-9 kcal/mol. l However, the only previous work which shed light on the overall thermodynamic effect of fluorine on a cyclopropane ...
