Abstract
Cu(I) complexes of monodentate ligands R-2,4-diphenyloxazoline (1) and R-2-isopropyl-4-pheny1loxazoline (2) exhibit significant increase of enantioselectivity in cyclopropanation of styrene versus ligands 3-6, indicating participation in thr catalytic cycles of conformationally d istinguishable 2:1 (ligand/Cu) complexes, stabilized by pi stacking of phenyl groups on the chiral centre.
