for complexes containing 1,2-bis(oxazolinyl)benzene, endo and exo, with the diasteromeric excess of ca. 40% for type 1 complexes and ca. 75% for type 2 complexes. The catalytic behaviour of the palladium systems with the ligands described was tested for a model allylicalkylationreaction. The Pd/bis(oxazolinyl)benzene ((R,R)-A, (S,S)-B) catalytic systems showed low activity, but good asymmetric inductions
