چکیده
In the title compound, [CuCl(2)(C(27)H(32)N(2))], which bears a chiral diamine ligand, viz (R,R)-N,N,N''- tribenzyl-cyclo-hexane-1,2-diamine, the Cu(II) ion is ligated by two N and two Cl atoms in a distorted square-planar geometry. The coordination of the ligands to the Cu(II) ion results in the formation of a five-membered heterocyclic ring and a chiral center at the monosubstituted nitro-gen in an (S)-configuration. The catalytic capacity of the complex for the asymmetric nitro-aldol reaction is promising (49% ee).
