Vicarious Nucleophilic Substitution of Hydrogen versus Bis – Annulation in the Reaction of Chloromethyl Aryl Sulfone Carbanion with Electrophilic Arenes
The carbanion of chloromethyl aryl sulfone reacts with 1-Cyanonaphthalene to form a bis-annulated product whereas with 1-nitronaphthalene vicarious nucleophilic substitution of hydrogen takes place.This result and the bis-annulation of quinoxalines and naphthyridines which was reported earlier are rationalized in terms of the negative charge delocalization in the intermediate ?-adducts.
