    Description / Table of Contents: Metal complexes with biologically important Ligands, IL. - Palladium and Platinum(II) complexes of Thioglycinate and ThioalaninateFrom chloro phosphane complexes and thioglycinate or thioalaninate the chelate complexes (1) (r2 = Et, Ph, n-Bu) and (2) (M = Pd, Pt) have been obtained. Spectroscopic data and the X-ray analysis of 1a (R1 = H; R2 = Et) indicate bonding of the α-Amino acylchloride complexes Cl2Pt(NH2CHRCOCl)2 react with thiophenol to give Cl2Pt(NH2CHRCOSPh)2 (4) (R = H, CHMe2).
    Notes: Aus Chloro-phosphan-Metallverbindungen werden mit Thioglycinat bzw. Thioalaninat die Chelat-Komplexe (1) (r2 = Et, Ph, n-Bu) und (2) (M = Pd, Pt) erhalten. Nach den spektroskopischen Daten und der Kristallstrukturbestimmung von 1a (R1 = H; R2 = Et) koordinieren die Anionen der α-Aminothiosäuren über die Aminogruppe und das S-Atom. Aus α-Aminosäure-chlorid-Komplexen Cl2Pt(NH2CHRCOCl)2 entstehen mit Thiophenol in heterogener Reaktion die Verbindungen Cl2Pt-(NH2CHRCOSPh)2 (4) (R = H, CHMe2) mit α-Aminothiosäure-S-phenylester-Liganden.

    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: Organometallic Lewis Acids, LIV.  -  Mo(CO)2(PPh3)2(O3SCF3)2: A New Precursor for an Organometallic Dicationic Lewis Acid with Three Accessible Coordination SitesThe reaction of Mo(CO)2(PPh3)2Br2 (1) with AgO3SCF3 gives the bis(triflate) complex Mo(CO)2(PPh3)2(O3SCF3)2 (3) which can be considered as a precursor for the 12-e- system “Mo-(CO)2(PPh3)2+2”. According to the spectroscopic data one of the two coordinated CF3SO-3 anions is acting as a chelate ligand. Treatment of 3 and of the in situ generated W(CO)2(PPh3)2(O3SCF3)2 (4) with H2O affords the dinuclear hydroxo-bridged complexes [M2(μ-OH)3(CO)4(PPh3)4][CF3SO3] (5: M = Mo; 6: M = W). Acetonitrile replaces the CF3SO-3 ligands in 3 and 4 to afford the cationic complexes [M(CO)2(PPh3)2(NCMe)3][CF3SO3]2 (7: M = Mo; 8: M = W). The reaction of 3 with an excess of 2-butyne and 1-phenyl-1-propyne leads to the monoalkyne complexes Mo(CO)(MeC≡CR)(PPh3)2(O3SCF3)2 (9: R = Me; 10: R = Ph) in moderate yield. In contrast, the bisalkyne complexes [M(CO)(MeC≡CMe)2(PPh3)2(O3SCF3)][CF3SO3] (11: M = Mo; 12: M = W) are formed in high yield when a CH2Cl2 solution of 2-butyne is added to 1 and 2 in the presence of AgO3SCF3. At room temperature, 11 and 12 are highly fluxional in solution, while 9 and 10 are stereochemically rigid. Treatment of 11 with acetonitrile yields [Mo(CO)(MeC≡CMe)2(PPh3)2(NCMe)][CF3SO3]2 (13). Compounds 3-13 (except 4) are characterized by IR, 1H-, 13C-, 19F-, and 31P-NMR spectrescopy.
