The manifestation of the “buttressing effect” – an indirect interaction between two substituents issued by the presence of a third group – and its influence on the ease and selectivity of the bromine-lithium exchange and the reactivity of formed aryllithiums is presented. In naphthalene substrates bearing twobromines, the impact on regioselectivity of the reaction is demonstrated.
