Reactivity in the Nucleophilic Aromatic Substitution Reactions of Pyridinium Ions
The “element effect” in nucleophilic aromatic substitution reactions (S(N)Ar) is characterized by the leaving group order, L = F > NO(2) > Cl ≈ Br > I, in activated aryl substrates. A different leaving group order is observed in the substitution reactions of ring-substituted N-methylpyridin...
