36. We also tried to optimize the reaction conditions, such as temperature, solvents and additives, for the homogeneous reaction, but the optimum conditions could not be found because of the formation of a palladium black in the homogeneous phase reaction.

38. We succeeded in the oxidation of allylic alcohols in our previous reported catalytic systems; refs. 9(b) and 10.
39. In several trials of the reaction using the recycled fluorous phase without the addition of a ligand, the precipitation of a palladium black was sometimes observed and the yield decreased. On the other hand, when further ligand was added for each run, the yield of the product gradually decreased, because a large excess of ligand lowered the reaction rate.
