Substitution Électrophile Aromatique II – Réactions De Démétallation des Triméthylphénylétain et Triméthylphénylplomb

Abstract
Arrhenius parameters have been determined for the protolysis of trimethylphenyltin. Rate equation of the iododemetalation of trimethylphenyltin and trimethylphenyllead have been established. Second order rate constants at 23°C have been calculated for these reactions. A positive salt effect has been observed for the iododemetalation of trimethylphenyltin.
