    • Key advantages of PS-PEG resin are as follows: (a) PS-PEG resin exhibits good swelling ability in a range of solvents (from water to toluene), which can be helpful in extraction of organic compounds and removal of reagent-derived ionic (or inorganic) co-products from the reaction beads. (b) It has been postulated that molecules (catalytic species) attached to the ends of long, flexible PEG chains are in a solution-like environment to show good activity in a given reaction.

    • After the reaction, the catalyst beads were removed by filtration and the resulting filtrate did not catalyze the allylic reduction to demonstrate no leaching of palladium species from the beads during the catalytic reaction.
