Kinetics and mechanism of the reaction of di-mu-hydroxobis(bipyridyl) dipalladium(II) ion with 1-cysteine at physiological pH in aqueous medium
Kinetics of interaction between L-cysteine with the title complex has been studied spectrophotometrically as a function of [Pd2(bipy) 2(OH)22+], [L-cysteine], pH and temperature. The reaction has been monitored at lambdamax 278 nm. The reaction rate increases linearly with increase in [L-cysteine] in the studied concentration range. The second order rate constants have been calculated from the slope of the Kobs versus [ligand] plot. From the experimental findings an associative mechanism for the substitution process is suggested. The activation parameters (DeltaH? =33.6¡À1.5 kJ mol -1, DeltaS? =-134¡À5 J K-1 mol -1) also support this proposition.
