Anhydrous 2-percarboxyethyl-functionalized silica (<b>2b</b>), a recyclable supported peracid, is a suitable reagent
to perform
the epoxidation of alkenes <b>1</b> in supercritical carbon
dioxide at 250 bar and 40 °C under flow conditions. This procedure
simplifies the isolation of the reaction products and uses only carbon
dioxide as a solvent under mild conditions. The solid reagent <b>2b</b> can be easily recycled by a reaction with 30% hydrogen
peroxide in an acid medium.
