Abstract

3 4 ization of the cations by 1, 3 overlap, one would expect the stabilization to increase as ring size decreased. One would therefore expect the para-proton resonance of the phenyl substituents on these cations to move upfield as one moved to smaller and smaller ring sizes. Although we have since shown that the para-proton resonance is in fact a very insensitive measure of carbonium ion stability, 2b and Taft has shown that the fluorine ...
