Elimination vs Substitution Reaction. A dicotomy between Bronsted-Lowry and Lewis basicity

Abstract

The Brønsted–Lowry and Lewis basicity dichotomy in the elimination vs substitution reaction competition is analyzed in terms of a novel Brønsted–Lowry–Lewis basicity ωp/e. This new index unifies the dichotomy and explains the competition between elimination and substitution mechanisms of alkyl centers with para-substituted phenols.
