Geometry of Meisenheimer Salts

Abstract

IN 1942 Wheland1 proposed a model for the activated complex in the aromatic electrophilic, radical and nucleophilic substitution reactions. This model was the object of semi-empirical quantum mechanical calculations and was formulated as follows where the asterisk stays for a plus charge, an unpaired electron or a minus charge, respectively.
