    • Since the concentration of Pd quoted in ppm/ppb is dependent on the amount of Pd initially added (lower levels at lower catalytic loadings) and the volume of solvent, Pd leaching will be quoted as a % of the initially added Pd.

    • The thiol content in both materials was determined by elemental analysis. Only materials with the same % thiol were compared

    • Note that these results were performed in air. The co-condensation-derived catalyst displays even less stability in argon

    • The catalysts are also somewhat sensitive to mechanical agitation.

    • note
    • This effect is likely due to the protective effects of the grafting layer insulating the silica against attack by the aqueous base. The addition of a protective layer has been shown to dramatically improve the stability of this material (K. McEleney, C.M. Crudden, manuscript in preparation).
