Article abstract of DOI:10.1039/DT9910003049

The kinetics of displacement of chloride from complex anions of the type ^- (pydca = pyridine-2,6-dicarboxylate; R = H, Cl or OMe) by a number of anionic and neutral nucleophiles have been studied in aqueous solution, at 25.0 deg C, I = 0.50 mol dm^-3 (LiClO4).Apart from the reactions with OH^-, the reactivities of the substrates are not greatly sensitive to the nature of the substituent in the 4 position.Anionic nucleophiles can be as much as two orders of magnitude less reactive than neutral nucleophiles with similar n⁰_Pt values.The rate law for the reaction with OH^- takes the form -dln/dt = k_s + k₃->², where k_s is the first-order rate constant for the solvolytic pathway observed in all the substitution reactions, and where k₃ is sensitive to the basicity of the nitrogen in the terdentate ligand.
