Fig. 4. (a) Iodination of cyclopalladated MPAA complex 6b; (b) plot of initial rate of iodination of 6bversus equivalents of exogenous iodide; (c) plot of initial rate of iodination of 6bversus initial concentration of I2 showing first order kinetics in I2 under saturating Bu4NI conditions; (d) overlaid reaction profiles of iodination of 6b from 3–39 mM I2 with exponential fits for pseudo-first order reactions; (e) overlaid reaction profiles of iodination of 6b in the presence and absence of Bu4NI with an exponential fit in the presence of Bu4NI and a linear fit for zero order portion in the absence of Bu4NI.
