    • note
    • The observed kinetic laws (Figure 1 and Figure S1 in the Supporting Information) establish that the reaction proceeds without significant induction period as if the concentration of catalytic species were rapidly maintained at a constant value during the reaction course; this constant value depends on the number of monolayers. According to one possible mechanism each type of NP acts as a reservoir in fast equilibrium with the soluble palladium species ("fast" with respect with the overall kinetics). Such behavior would maintain a time-constant ML-dependent catalyst(s) concentration in the solution and compensate automatically for their expected low life-time in the absence of suitable ligands.

    • We did not use a strong surfactant as in Ref. [13a] so that the Pd excess residual was smaller (11-%) than that reported by Wang et al.
