Abstract:
Two New organoplatinum(II) and organoplatinum(IV) complexes containing chelated ligand with nitrogendonor atoms, (L), were synthesized and characterized by different methods such as: FT-IR, 1H NMR, UV/Vis,elemental analysis and conductometry. Kinetic studies of the oxidative addition reaction of MeI withorganoplatinum(II) complex were investigated and the temperature dependence of the rate constant was reported. Fromthe temperature dependence of rate constants, the activation parameters were calculated. The activation parameterscontaining Ea, ΔH# and ΔS# of the reaction were calculated according to Arrhenius and Eyring equations, respectively.The large negative of ΔS# showed that the reaction occurred by the SN2 mechanism.
