Chiral Octahedral Complexes of CoIII As a Family of Asymmetric Catalysts Operating under Phase Transfer Conditions

Stereochemically inert and positively charged chiral complexes of Co-III prepared from Schiff bases derived from chiral diamines and salicylaldehydes were shown to be efficient catalysts of the asymmetric phase transfer benchmark reaction of alkylation of O'Donnell's substrate with alkyl halides. The enantiomeric purities of the reaction products were up to 92%.
