Abstract The title reaction has been studied by 1 H NMR, both in CD 3 OD and in tBuOK/CD 3 OD. The components of the electronic effect of the substituent on the benzene ring show different contributions depending on whether the equilibrium between neutral (strong prevalence of the “proximity polar effect”) or anionic species (balance between “ordinary and proximity polar effects”) is considered. The “primary steric effect” does not significantly ...
