    • Owing to the very large errors affecting the determination of the concentrations, standard errors of the van't Hoff regression are not reported. Therefore, the equilibrium constant values must be considered as rough estimates of their order of magnitude.

    • The NSMe species represents the less strongly bonded ligand among all the ligands used in this work. Therefore, its added concentration would represent the limiting concentration also in the case of NSt-Bu DPPQ and DPPQMe are not displaced by isocyanide

    • Strictly speaking, eq 3 turns into eq 4 at very high chloride concentration according to the limit: lim (KClki, k2[Cl-], KCl[CNR2, Cl-, k2 for [Cl, → ∞o. In practice, the amount of added chloride was the concentration at which the rate of reaction levels off to an asymptotic value (k 2, This value is reached even at 3-4 times the concentration of the starting complex [Pd(NSMe)(Me)Cl, We however decided to add a 10-fold excess in all cases studied in order to ensure the constancy of chloride concentration with time. Moreover, under this condition the extent of reaction for the chloride displacement equilibrium (KCl) is virtually zero, equilibrium (1) being completely shifted to the left, b) Analogously to those calculated in the presence of an excess of halide, approximate k2 values were d
    • 2 values were determined in the absence of added chloride by numerical regression of the absorbance vs time data according to the second-order treatment. Such values are purely indicative since the treatment is obviously inadequate owing to the complexity of the overall reaction mechanism. Nevertheless, the comparison among rates is warranted by the fairly satisfactory fit obtained.
