 Title    Metallkomplexe mit biologisch wichtigen Liganden, LXXXIV [1] Halbsandwich-Komplexe von Rhodium(III), Iridium(III), Cobalt(III), Ruthenium(II), Ruthenium(III) und Chrom(III) mit Aminosäureester-Liganden Metal Complexes with Biologically Important Ligands, LXXXIV [1] Half-Sandwich Complexes o f Rhodium(III), Iridium(III), Cobalt(III), Ruthenium(II), Ruthenium(III) and Chromium(III) with Amino Acid Ester Ligands  
 Abstract    A series of cyclopentadienyl and pentamethylcyclopentadienyl complexes of cobalt, rhodium, iridium, ruthenium and chromium with a-amino-acid esters (L) as ligands was prepared and characterized: Cp*(Cl)2M(L) (1, 2: M = Rh, Ir), Cp(I)2Co(L) (4), [Cp(Ph3P)2Ru(L)]+BF~ (6), [Cp(OC)(Ph3P)Ru]+BF^ (7) and the paramagnetic compounds Cp*(Cl)2Ru(L) (8) and Cp(Br)2Cr(L) (9). AlaOMe and HisOMe form N ,0 and N,N chelate complexes [Cp*(Cl)M(alaOMe)]+BF~ (3: M = Rh, Ir), [Cp(I)Co(hisOMe)]+BF4. Cp*Co(CO)I2 and GlyOMe gave the N,0-dipeptide ester complex Cp*(I)Co(glyglyOMe)]+BF^ (5). The crystal structures of Cp(I)2Co(glyOEt) and Cp*(Cl)2Ru(alaOMe) were determined by X-ray diffrac­ tion. The complexes 1 and 2 undergo ester exchange reactions with CD3OD. [Cp*MCl2]2 (M = Rh, Ir) catalyze the exchange of the ethoxy group in Me2NCH2C 0 2Et by CD3OD.
