A series of the anionic CoIII complexes based on optically active amino acids containing the lithium cation in the external sphere of the complex was synthesized. The synthesized compounds were used as catalysts in the asymmetric addition of trimethylsilyl cyanide to aldehydes. The influence of the temperature, catalyst concentration, and modification of the chiral anion structure on the enantioselectivity of catalysis was studied.

Key words asymmetric trimethylsilylcyanation chiral anions, lithium cation Lewis acid, cyanohydrins
