Sulfonated chiral Mn(salen) catalyst immobilised onto various supports such as silica, LDH and resin afforded remarkably higher rates and ees of up to 96% for the asymmetric epoxidation of unfunctionalised olefins. The LDH and resin supported ( R,R )‐ 1 catalysts were recovered quantitatively by simple filtration and reused for several times with consistent ees and insignificant loss of activity.
