NMR and mass spectral data of seventeen monosubstituted fluoroalkylcyclopropanes are presented; the shielding effect of the fluoroalkyl groups on the ring-protons are discussed.Fluorine substitution on the carbon a to the ring not only deshields all the ring protons, but also produces anothor interesting effect.Wheroas ordinary alkyl side-chain causes a difference in shielding on the cis and trams protons with a Δδ-value of ~0.4ppm,the Δδ-values of the above mentioned cyclopropanes a,re a function of the number of fluorine atoms substituted on the a-carbon.
