The kinetics and equilibria of the reversible reactions trans-(+)+X(n-) = mer-1-n have been studied in methanol .The second-order rate constants of the forward reactions are scarcely affected by the nature of the entering group, whereas the first-order rate constants of the reverse reactions are strongly influenced by the leaving group involved.A linear free-energy relationship of the type with a value of α of 0.75 exists for the activation and standard free energies of mer -->trans reactions where a dissociative mechanism is considered to be operative.When X(n-) is SCN(-), N3(-), or NO2(-), the mer -->trans reactions are acid-catalyzed, through protonation of the leaving group.
