    Notizen: From the amino glycoside neomycin B, the acetate-protected hexaisocyanide 4 has been prepared. 4 forms the hexanuclear complexes [(4)(AuCl)6] (5), {(4)[Cr(CO)5]6}, {(4)[MCl2(η5-C5Me5)]6} (M = Rh, Ir), {(4)[RuCl2(p-cymene)]6}, {(4)-[MCl2(PR3)]6} (M=Pd, Pt), and 4{(4)[PdCl(C6H4CH2NMe2)]6). The hexaisocyanohexagold(I) complex 5 reacts with H2NtBu and PhNH2 to give the corresponding carbene complexes. The compounds have been characterized by IR, 13C- and 31P-NMR spectroscopy, and (partially) by FAB-MS data.

    Notizen: Metal Complexes of Biologically Important Ligands, LXVIII[1]. - Organometallic Asparaginato Cobalt Complexes as Ligands for Alkaline IonsThe trischelate complexes of the dianion of aspartic acid and β-methylaspartic acid (η5-C5Me5)] (R = H, Me) form adducts with alkali iodides MI (M = Li, Na, K). The polymeric structure of (η5-C5Me5)Co(L-asp.-2H+)KI (1c) was determined by X-ray diffraction. In the crystal of 1c the potassium ions are surrounded by five oxygen atoms of the carboxylate groups whereby two oxygen atoms form bridges between two K+ ions. Similarly, trischelate complexes 4 and 5 have been obtained from (η5-C5Me5)Co(CO)I2 and 2,3-diaminopropionic, 2,4-diaminobutyric acid, and asparagine, respectively.

    Notizen: 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.

    Notizen: 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).

    Notizen: Metal Complexes of Dyes, III[1,2]. - Transition Metal Complexes of Pyrrole Indigo The dianions of octahydroindigo and 4,4′-dibutyl-5,5′-dimethylpyrrole indigo (L) react with metal salts and chloro-bridged complexes [(μ-Cl)M(Cl)PR3]2 (M = Pd, Pt; R = nBu, Et), [(μ-Cl)M(Cl)(η5-C5Me5)]2 (M = Rh, Ir) to give the bis-N,O chelate complexes [M(L - 2H+)]n (M = Cu, Zn), (L - 2H+)[M(Cl)(PR3)]2 (M = Pd, Pt), and (L - 2H+)[M(Cl)(η5-C5Me5)]2 (M = Rh, Ir). The electronic spectra of the soluble complexes with phosphane or C5Me5 ligands show a large bathochromic shift of the absorptions in the visible region compared to the free neutral ligands which is in accordance with PPP calculations of model compounds.

    Notizen: 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.

    Notizen: The palladium-mediated coupling of p-ethynylphenylalanine (p-epa) with different halogenated benzenes yielded alkyne-bridged α-amino acids. A series of cationic mono- to hexanuclear (Ph3P)2Pt complexes with the anions of p-ethynylphenylalanine and alkynyl- or benzene-bridged di-, tri-, tetra- and hexa-ethynyl phenylalanines as N,O-chelate ligands was prepared. N-t-Boc-p-ethynylphenylalanine methyl ester was metal-substituted to give complexes of the types Ph3PAu-C≡C-R and (Et3P)2Pt(C≡CR)2. The benzene-bridged di-, tri-, tetra- and hexa-p-ethynylphenylalanine methyl esters form Schiff bases with ferrocene aldehyde and a tripodal ligand was obtained from Ph2PCH2CH2CH2NH2 and the benzene-bridged tri-ethynylphenylalanine. The structure of (Ph3P)2Pt[NH2C(H)(CH2C6H4C≡CH)CO2]+ BF4- was determined by X-ray diffraction.
