Özet:

 

NHC--Pd(II) complexes bearing a chiral oxazoline ligand  (IIIa--f) were synthesized by cleavage of dimeric  palladium complexes with the oxazoline ligand. They were fully characterized  by 1H and 13C NMR and elemental analyses. The catalytic activity  of the complexes (IIIa--f) in allylic alkylation reactions  was evaluated. The complex IIIa was found to be the most active  catalyst. Very low ee values indicate that the oxazoline is dissociated from  the active catalytic species.
