Abstract
Copper(II) complex of the ligand possessing two enantiomerically pure trans-cyclohexane-1,2-diamine units proved to be an efficient catalyst for the enantioselective Henry reaction of aromatic aldehydes with nitromethane. The effect of various reaction conditions on yield and enantioselectivity of the Henry reaction was studied. The results suggest that only one cyclohexane-1,2-diamine unit is involved in catalysis of the Henry reaction.

The present study of the catalytic properties of the copper(II) complexes of bis(trans-cyclohexane-1,2-diamine)-based ligand 1 answered a question of whether the secbis(trans-cyclohexane-1,2-diamine)-based ligand 1 answered a question of whether the ond copper (II) ion in the dinuclear copper(II) complex might somehow contribute to catalsecond copper (II) ion in the dinuclear copper(II) complex might somehow contribute to ysis of the enantioselective Henry reaction
