Abstract

Recently, it has been found that room-temperature ionic liquids can be used as stable, unusual selectivity stationary phases. They show “dual nature” properties, in that they separate nonpolar compounds as if they are nonpolar stationary phases and separate polar compounds as if they are polar stationary phases. Extending ionic liquids to the realm of chiral separations can be done in two ways:(1) a chiral selector can be dissolved in an ...
