Asymmetric catalysis with CO2: direct synthesis of optically active propylene carbonate from racemic epoxides.
This communication describes a convenient route to optically active propylene carbonate by a catalytic kinetic resolution process resulting from the coupling reaction of CO2 and racemic epoxides using simple chiral SalenCo(III)/quaternary ammonium halide catalyst systems.
