Abstract

By comparison of the ¹⁹F chemical shift of p-fluorophenyl substituted Coates cation 1 with that of triasteryl cation 2, πσ-participation by the remote cyclopropyl group in ion 1 is shown to be more effective than σ-participation by the adjacent cyclopropyl group in ion 2 in the delocalization of positive charge.
