Dichlorido[(R,R)-N1,N1,N2-tribenzylcyclohexane-1,2-diamine-κ2N1,N2]copper(II)

Abstract

In the title compound, [CuCl2(C27H32N2)], which bears a chiral diamine ligand, viz (R,R)-N,N,N′′- tribenzylcyclohexane-1,2-diamine, the CuII ion is ligated by two N and two Cl atoms in a distorted square-planar geometry. The coordination of the ligands to the CuII ion results in the formation of a five-membered heterocyclic ring and a chiral center at the monosubstituted nitrogen in an (S)-configuration. The catalytic capacity of the complex for the asymmetric nitroaldol reaction is promising (49% ee).
