Epoxidation of Olefins with a Silica-Supported Peracid in Supercritical Carbon Dioxide under Flow Conditions Rossella Mello Ana Alcalde-Aragonés Andrea Olmos María Elena González-Núñez Gregorio Asensio 10.1021/jo300532f.s001 https://acs.figshare.com/articles/journal_contribution/Epoxidation_of_Olefins_with_a_Silica_Supported_Peracid_in_Supercritical_Carbon_Dioxide_under_Flow_Conditions/2521477 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. 2012-05-18 00:00:00 carbon dioxide Olefin Peracid acid peracid Epoxidation alkene medium Flow epoxidation isolation flow peroxide ConditionsAnhydrou reagent 2 b procedure Supercritical Carbon Dioxide
