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

Stereochemically
inert and positively charged chiral complexes
of CoIII 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%.

由手性二胺和水杨醛衍生而来的席夫碱制备的立体化学惰性和正电荷的钴(III)手性复合物，已被证明是O’Donnell底物与烷基卤化物进行非对称相转移基准反应的高效催化剂。该反应产物的对映选择性高达92%。
