    Notes: Hydrocarbon-Bridged Metal Complexes, XX. - Nucleophilic Addition of Carbonyl Metallates to Cationic Hexadienyl, Cyclohexadienyl, Cycloheptadienyl, and Cyclooctadienyl Complexes of Iron and Ruthium: Heterobimetallic Complexes with η1:η4, -C6, -C7, and -C8 Hydrocarbon BridgesThe addition of Re(CO)-5, Mn(CO)-5, and [(η5-C5H5)W(CO)3]- to the cationic dienyl complexes [(η5-dienyl)M(CO)3]+ (M = Fe, Ru; dienyl = hexadienyl, cyclohexadienyl, cycloheptadienyl, cyclooctadienyl, bicyclo[5.1.0]octadienyl) gives the heterobimetallic η1:η4-hydrocarbon-bridged complexes 1 - 4, 6, 7. In solution the initial nucleophilic adduct 2e of [(η5-cyclo-hexadienyl)Ru(CO)3]+ and [Re(CO)5]- rearranges to the complex 3, in which the Re(CO)5 group is bound to a sp2 carbon atom. By using Mn(CO)-5 also the products of electron transfer between cation and anion have been observed. The crystal structures of (OC)3Fe(μ-η4:η1-hexadiene)Re(CO)5 (1), (OC)3Ru(μ-η4:η1-cyclohexadiene)Re(CO)5(3), (OC)3Fe(η4:η4-C7H9 - C7H9)Fe(CO)3 (5), (OC)3Ru(μ-η4:η1-cyclooctadiene)Re-(CO)5 (6b), and of (OC)3Fe(η4:η1-bicyclo[5.1.0]octadiene)-Re(CO)5 (7) have been determined by X-ray diffraction.

    Notes: Metal Complexes with Biologically Important Ligands, LXV[1].  -  Chiral Half-Sandwich Complexes of Cobalt(III), Rhodium(III), Iridium(III), and Ruthenium(II) with α-Amino Amide, Glycinenitrile, and Peptide Ester LigandsCp*Co(CO)I2 (Cp* = η5-C5Me5), [(η6-arene)RuCl2]2 (arene = p-cymene, hexamethylbenzene), and [Cp*MCl2]2 (M = Rh, Ir) react with α-amino amides and various peptide esters to give the N,O-chelate complexes [Cp*(I)Co  -  NH2C(H)(R1)C(NHR2)-O]+ (1), [(η6-arene)(Cl)Ru  -  NH2C(H)(R1)C(NHR2)O]+ (2), and [CP*(Cl)M - NH2CH2C(NHR)O]+ (M = Rh, Ir) (5, in solution), respectively. In the solid state the ligands are η1N-bonded in 5. By deprotonation of the peptide bond in 2 and 5 the neutral N, N-chelate complexes (η6-arene)(Cl)Ru  -  NH2C(H)(R1)C(O)-N̊2 (6) and Cp*(Cl)M  -  NH2C(H)(R1)C(O)NR2 (M = Rh, Ir) (7) have been obtained. Glycinenitrile is η1-bonded in (η6-p-cymene)(Cl)2Ru(NH2CH2CN) (3) and Cp*(Cl)2Rh(NH2CH2CN) (4). Double deprotonated triglycine methyl ester is a N,N,N-tridentate ligand in (η6-C6Me6)Ru(NH2CH2C(O)NCH2C(O)-NCH2CO2Me) (8). The anions of L-asparagine and of aspartame (L-aspartyl-L-phenylalanine methyl ester) give the complexes 9-12 with tridentate O,N,O- or O,N,N-chelate ligands. The crystal structures of 1d (L = glyglyOEt), 5a (L = glycinamide), 6e (L = glyglyOEt), and 7k (L = glyglyglyOEt) have been determined by X-ray structural analysis.

    Notes: Metal Complexes of Biologically Important Ligands, LVIII. - C-Allylglycine and C-Vinylglycine Complexes of Palladium(II), Platinum(II), Rhodium(III), Iridium(III) and Reactions with NucleophilesThe synthesis of the complexes (R13P)(Cl2Pt(C-allylglycine ester) (1), (2) and of (η5-C5Me5)Ir(C-allylglycinate) (6) with tridentate O,N,η2;-C—C allylglycinate as ligand is described. Addition of enolates (Nu-) to the coordinated C=C bond of 2 gives the γ-C-metallated α-amino acid ester complexes (3). In most cases the platination occurs stereoselectively to yield the five-membered metallacycle with the substitutents CH2Nu and CO2R2 in trans position. From 3d the new α-amino acid H2NCH(CO2Me)-(CH2)3C(Ph)(CO2Et)21 (4) is cleaved. The structures of 3c and 6 have been determined by X-ray diffraction. C-Vinylglycinate can be stabilized at the metal atom in the complexes (10) (M=Rh, Ir).

    Notes: The following chiral organometallic complexes of the cinchona alkaloids quinine (L1), cinchonidine (L2), quinidine (L3), cinchonine (L4) were prepared: [(η5-C5H5)(Ph3P)(OC)-Ru(L)]BF4 (1: L=L1; 2: L=L2; 3: L=L3), ClAuL1 (4), [(η5-C5Me5)(Cl2)Ir(L)] (5: L=L1; 6: L=L2; 7: L=L4), [(η5-C5Me5)(Cl2)Rh(L2)] (8), [(η6-p-cymene)(Cl2)Ru(L)] (9: L=L1; 10: L=L2; 11: L=L4). In all complexes the tertiary nitrogen atom of the cinchona alkaloids is bound to the metal. Complexes 5 - 11 are formed as mixtures of isomers. Elimination of HCl from 10 and 11 gives the neutral N,O-chelate complexes (η6-p-cymene)(Cl)Ru(L2 - H+) (13) and (η6-p-cymene)-(Cl)Ru(L4 - H+) (14) which were structurally characterized by X-ray diffraction.

    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.
