Asymmetric catalytic epoxidations of simple olefins

Two types of chiral (salen)Mn(III) complexes, either cationic or neutral, were synthesized by complexation of the corresponding chiral salen ligands with manganese salt. Neutral Mn(III) salen complexes were prepared from the ligands and $\rm Mn(OAc)\sb2{\cdot}4H\sb2O$ via in situ aerial oxidation of the corresponding (salen)Mn(II) species. This approach circumvents the manipulation of highly air sensitive Mn(II) salen intermediates. The use of commercially available bleach solution as the oxidant greatly increases the practical value of this asymmetric epoxidation process.
