Non-covalent interactions such as coordination of an organolithium reagent by a directing group and steric repulsion of substituents strongly affect the halogen-lithium exchange process. Here we present 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 ...
