Hydrotalcite-Promoted Epoxidation of Electron-Deficient Alkenes with Hydrogen Peroxide.

A synthetic anionic clay, hydrotalcite (MgAl = 2.8), promotes the epoxidation of electron-deficient alkenes with H2O2. With open-chain, α,β-unsaturated carbonyl compounds 3-hydroxy-1,2-dioxolanes are also obtained.
