2-Ferrocenyl-4R-5(4H)-oxazolones 1-5 were obtained from N-ferrocenoyl-α-amino acids and function as N donors in dichloro-phosphine-palladium(II) and platinum(II) complexes 6-18. The reaction of ferrocenyl-oxazolone and ferrocenyl-bis(oxazolone) with [Cp*IrCl2]2 afforded trimetallic and pentametallic complexes 19 and 20 with a C,N bridging oxazolone. Ring opening of the ferrocenyl-oxazolones 1, 2 and 4 with α-amino acid esters gave N-ferrocenoyl-dipeptide esters 21-26. In the ferrocene bis(dipeptides) the two peptide esters are aligned parallel by hydrogen bonding. The structures of 6 and 19 were determined by X-ray diffraction.
