4H)-oxazolone (1) forms with the chloro bridged compounds [R3PMCl2]2 (M = Pt, Pd) the complexes Cl2Pt(PR3)(l) (R = Et, nBu) and Cl2Pd(PEt3)(l). The enantiomeric pure C2-symmetric CMe2 bridged bis(oxazolones) 5 and 6 have also been employed which give with PdCl2 the chelate complexes 13 and 14. The X-ray structural determination of Cl2P d[O-C (O)-CMe2-N=C-CMe2-C=N-CMe2-C (O)-O ] (10) shows that one
