The π-Fluoro Effect: An Empirical Use of Atomic Electrostatic Potentials

  • Joel F. Liebman

The term “π-fluoro effect” refers to the experimental observation that in many molecules, the ionization potentials of π-electrons change relatively little when a hydrogen atom is replaced by a fluorine. This was first systematically studied, although in a more limited sense, by Brundle, et al.,1 and was called the “per-fluoro effect”.
