    Notes: The synthesis and characterization of heterobimetallic and mixed-valence complexes in which orthometalated [(ppy)2MCl] (M = Rh, Ir; ppy = 2-phenylpyridine anion) and [(bzq)2RhCl] (bzq = benzo[h]quinoline anion) fragments are linked via chloro-bridges with rhodium(I), iridium(I), palladium(II), and platinum(II) fragments is reported. These complexes are formed in nearly quantitative yields by metathesis reactions from the respective homodimeric compounds. The structures of [(ppy)2Rh(μ-Cl)2Rh(cod)] (cod = η4-1,5-cyclooctadiene) and [(ppy)2Rh(μ-Cl)2Pt(PBu3)-Cl] were determined by X-ray structure analyses.

    Catalytic Formation of Oligopeptides from α-Amino Acid Esters with (p-Cymene)ruthenium(II) Complexes (1998)

    Notes: Consecutive addition of one-equivalent portions of glycine ethyl ester to [(p-cymene)Ru(GGGOMe-H+)Cl] leads to considerable amounts of (tetra- to nonapeptide)ruthenium complexes in a one-pot reaction, in which the (p-cymene)RuCl fragment acts as a catalyst. The analogous reaction with alanine methyl ester affords AGGG and AAGGG complexes as the main products. The course of these metal-catalyzed peptide oligomerizations has been followed by mass spectrometry. The synthesis and characterization of the pentapeptide complex [(C6Me6)Ru(GGGGGOMe-H+)] is reported.
