Reaction of the starting materials with water:

3,4-Epoxy-1-butene (5.53 mg, 78.9 µmol) was added to 0.7 ml of a D2O stock

solution of 2.10 (at a concentration of 10 mg mL-1). The solution was agitated for 24

Recycling experiment

After the products were extracted from the initial reaction with CDCl3, the aqueous

polymer solution of 2.09 was dried under vacuum to remove any residual CDCl3.

Then, the catalysis reaction was repeated as described in the experimental section.

Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) Study

After performing the catalysis at 0.1 mol% and extraction of the products by CDCl3,

the aqueous solution was analysed by ICP-OES and showed a Pd concentration of 867 ppb (expected concentration was 837 ppb). Then, poly(vinyl pyridine) (PVP) (34.3 mg) particles were added to the solution to bind any free palladium that leached out of the micelles during the reaction. The solution was stirred for 2 h and then left to stand for 1 h to allow the PVP particles to settle. Next, the solution was analysed by ICP-OES, which gave a Pd concentration of 521 ppb, indicating that approximately 40% of the Pd had been removed by the PVP particles.

Hg drop test: The catalysis was performed as described earlier, but with the addition of Hg (80 mg) to the solution.

PVP Test: The catalysis was performed as described earlier, but with added PVP (10
