Transition Metal-free Epoxidation of Alkenes Based on the Existence of (2-hydroxypropyl)-β-CD

摘要

A green, efficient epoxidation of alkenes with hydrogen peroxide (H2O2) and sodium bicarbonate (NaHCO3)catalyzed by (2-hydroxypropyl)-β-cyclodextrin (2-hp-β-CD) in aqueous solution has been investigated in detail. A rangeof alkenes were epoxidized at ambient temperature with high yields.
