Popis:	Cu(I) complexes of monodentate ligands R-2,4-diphenyloxazoline (1) and R-2-isopropyl-4-phenyloxazoline (2) exhibit significant increase of enantioselectivity in cyclopropanation of styrene versus ligands 3–6, indicating participation in the catalytic cycles of conformationally distinguishable 2:1 (ligand/Cu) complexes, stabilized by π stacking of phenyl groups on the chiral centre.
