Abstract

The highly regioselective conversion of epoxides into corresponding vicinal halohydrins with elemental halogen are catalyzed by imidazolidine derivative. This method occurs under neutral and mild conditions with high yields in various aprotic solvents even when sensitive functional groups are present.
