Epoxidation Of Alkenes

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