Enantioselective addition of diethylzinc to a series of aromatic aldehydes is developed using new chiral C 2 -symmetric ligand (S)-2,2 0 -(1,1 0 -binaphthyl-2,2 0 -diylbis(oxy))bis(methylene)bis(4-nitrophenol) (S)-2b. The catalytic system employing 10 mol % of (S)-2b and 120 mol % of Ti(OiPr) 4 was
