실험 절차

Crosslinked polystyrene-divinylbenzene beads substituted in the phenyl rings by arsono groups (Polymer II of Example 2 (B) above, containing 0.25 mmole As) was added to a two phase system of 1.7 g of 30% aqueous H2O2 (15 mmoles of H2O2) and cyclooctene (7.5 mmoles) in chloroform (7 ml). The mixture was heated in a closed thick-walled tube at 70° C. for 45 hours. Cyclooctene oxide (6.7 mmol, 89% yield) was obtained after 45 hours. The polymer was then filtered and reused with no apparent loss of activity (90% yield after 55 hours at 70° C.).
