摘要: The kinetics and mechanism of the complex-formation reactions [Pd(met)Cl2]–(met =L-methionine anion) with inosine 5′-monophosphate were studied in detail as a function chloride nucleophile concentrations, temperature pressure weakly acidic aqueous solutions. Two consecutive reaction steps which both depend on concentration observed. A comparison rate data for corresponding ethylenediamine substituted complexes reveals significant lability induced by S-donor chelate [Pd(met)Cl2]–. reported activation parameters underline operation an associative ligand-substitution under all conditions.
