Lieber, Charles M. published the artcileKinetic studies of ligand substitution rates for the Ru(NH3)5(H2O)2+ ion in Nafion films, Synthetic Route of 530-40-5, the publication is Journal of the American Chemical Society (1986), 108(20), 6103-8, database is CAplus.
Substitution rates were measured for reaction of a number of pyridines with the Nafion-bound Ru(NH3)5(H2O)2+ complex. Reaction activities were determined by electrochem. techniques, which also allow for determination of site thermodn. and heterogeneity during the course of the reaction. Diffusion-coefficient effects were investigated by variation in polymer film thickness, and partition coefficients were determined under equilibrium conditions by optical absorbance techniques. The partition-coefficient corrected rate law is 1st order in Nafion-bound [RuII] and first order in ligand concentration in the polymer phase. The partition-coefficient corrected bimol. rate constants for a variety of pyridine ligands vary by a factor of 5, which contrasts with the relatively constant substitution rates observed in aqueous solution Also, sterically hindered ligands, such as 2-pyropylpyridine, have surprisingly high substitution rate constants on the Nafion-bound RuII ion. These rate data indicate that pronounced mol. reactivity changes can occur upon electrode modification and have implications with respect to the design of chem. modified electrodes for use in electrocatalysis.
