    • Abstract

       

      The reactivity of cis-[Pt(pipen)(H2O)2]2+ (pipen=2-aminomethylpiperidine) was investigated by studying the interaction with some didentate N,N-donor ligands, namely, dimethylglyoxime (L1H), 1,2-cyclohexanedionedioxime (L2H) and α-furildioxime (L3H) in an aqueous medium. All the above substitutionreactions have been monitored spectrophotometrically at 320, 308 and 290 nm, respectively, where the spectral difference between the reactants and the products are appreciable. The kinetic study has been substantiated byproduct isolation, UV, IR and ESI-MS spectroscopic analysis. The rate parameters have been evaluated under different reaction conditions. The reactions were found to occur in two consecutive steps. The mechanism ofthe substitution reactions appears associative in nature as supported by the large and negative values of ΔS
