A new chiral complex of [N,N’-bis(2,6-dichlorobenzyl)-(R,R)-1,2-diaminocyclohexane] dichloro zinc(II) was synthesized and its X-ray crystal structure was determined. X-ray structure data shows that geometry around the central Zn metal is nearly tetrahedral. The coordination of the metal to the chiral amine ligand leads to a 5-membered heterocyclic ring that blocks nitrogens also in distorted tetrahedral structures exhibited in (S, S)-configuration. Asymmetric nitroaldol reaction between benzaldehyde and nitromethane in the presence of amine bases and this chiral complex as enantioselective catalyst was examined.
