While molecular oxygen is regarded as an environmentally friendly oxidant, applications are sometimes limited due to safety reasons. In addition, the use of molecular oxygen in combinatorial flow systems is rare.

    • 4 was better for the flow system. Although the precise reason is not clear at this stage, the rate difference of the absorption of water may explain the results.

    • While polymer-supported perruthenate was used for oxidation of alcohols in a batch system, its catalytic activity was lower than that of PI-Ru. See: (a) Hinzen, B.; Ley, S. V. J. Chem. Soc., Perkin Trans. 1 1997, 1907.
