    Description / Table of Contents: Sulfur Dioxide as Ligand and Synthon. IX. Reactions of Cobalt Carbonyls with Sulfur Dioxide - Synthesis and Characterization of Alkoxysulfinyl-Cobalt Carbonyl ComplexesReactions of phosphine substituted Co2(CO)8, (Ph2P-(CH2)n-PPh2: n = 1, dppm; n = 2, dppe; n = 3, dppp; n = 4, dppb), alkylcobalt carbonyls and alkoxycobalt carbonyls with sulfur dioxide have been investigated. The SO2 containing cobalt complexes are characterized by means of I.R., 1H-NMR, and mass spectra. Further on synthesis and properties of new alkoxysulfinylphosphine-cobalttricarbonyl complexes of the type ROS(O)Co(CO)3PR31 (R = Ph3Si, Me; R1 = Et, i-Pr, Ph) are described.
    Notes: Reaktionen von phosphinsubstituiertem Co2(CO)8, (Ph2P-(CH2)n-PPh2: n = 1, dppm; n = 2, dppe; n = 3, dppp; n = 4, dppb), Alkylcobaltcarbonylen sowie Alkoxycarbonyl-Cobaltcarbonylen mit Schwefeldioxid wurden untersucht. Die Charakterisierung der gebildeten SO2 enthaltenden Cobaltkomplexe erfolgte mit Hilfe der IR-, 1H-NMR- und Massenspektroskopie. Darüber hinaus werden Synthese und Eigenschaften neuer Alkoxysulfinyl-Phosphin-Cobalttricarbonyl-Komplexe des Typs ROS(O)Co(CO)3PR31 (R = Ph3Si, Me; R1 = Et, i-Pr, Ph) beschrieben.

    Description / Table of Contents: Beiträge zur Chemie der Alkylverbindungen von Übergangsmetallen. 56. 2-(Dimethylaminomethyl) ferrocenyl-Derivate des Titans und Zirconiums - Grenzen der ChelatbildungAls neue Titanocen- bzw. Zirconocenkomplexe wurden das paramagnetische (η5-C5H5)2Ti(FcN) III (FcN = 2-[Dimethylaminomethyl]ferrocenyl) und das diamagnetische (η5-C5H5)2Zr(1-Camph)(FcN) IV (1-Camph = 1-Camphenyl) synthetisiert und durch Massen-, 1H- und 13C-NMR-Spektren sowie magnetische Messungen charakterisiert. Ferner wurden die Kristall- und Molekülstrukturen von (η5-C5H5)2M(FcN)2 (M = Ti I, Zr II) bestimmt. Eine M—C, N-Chelatbildung mit dem (Dimethylaminomethyl)ferrocenyl-Liganden wurde bei III (im Festkörper) und IV (in Lösung) gefunden, während diese bei I und II im kristallinen Zustand ausbleibt.
    Notes: The new paramagnetic (η5-C5H5)2Ti(FcN) III (FcN = 2-[dimethylaminomethyl]-ferrocenyl) and diamagnetic (η5-C5H5)2Zr(1-Camph)(FcN) IV (1-Camph = 1-Camphenyl) complexes were prepared and characterized by spectra and magnetic measurements. The crystal and solid phase molecular structures of (η5-C5H5)2M(FcN)2 (M = Ti I and Zr II) compounds were determined by single crystal X-ray diffraction. An M—C, N chelation of the (dimethylaminomethyl)ferrocenyl ligand was detected at compounds III (solid phase) and IV (solution), while such interaction fails at complexes I and II in crystalline phase.

    Description / Table of Contents: Titanium-, Zirconium- und Hafniumderivate von CobaltcarbonylenBimetallische und trimetallische Verbindungen mit M-Co-Bindungen (M = Ti, Zr, Hf) werden erhalten durch Reaktionen von R41-Derivaten (R1 = PhCH2; R22N; R2 = Me, Et) mit HCo(CO)4 (A) bzw. durch Umsetzung von R31MX-Derivaten (X = CI, Br; R1 = PhCH2, R22N und R3O; R3 = i-Pr, n-Bu) mit Na[Co(CO)4] (B). Dabei wurden Verbindungen des Typs R31MCo(CO)4 mit R1 = PhCH2, R2)2N und solche des typs R21M[Co(CO)4]2 mit R1 = PhCH2 nach den Methoden A und B gewonnen während (R3O)4-n Ti[Co(Co)4]n-Derivate (n = 1,2) nur gemäß Methode B zugängig waren.Phosphan- und Phosphitderivate der angeführten Verbindungen wurden erhalten bei Substitution von jeweils einer CO-Gruppe durch PR34-Liganden bzw. durch Reaktion von HCo(CO)3(PR34 mit R41M Verbindungen. Der Einfluß der Substituenten R1 und PR34 auf die Stabilität der Verbindungen wird diskutiert.
    Notes: Bimetallic and trimetallic compounds containing unsupported bonds of subgroup 4 metals (M = Ti, Zr, Hf) and Co were prepared by hydride elimination (A) from R41M derivatives (R1 = PhCH2; R22N; R2 = Me, Et)) and by salt elimination (B) from R31MX (X = Cl, Br; R.1 = PhCH2, R22N and R3O; R3= i-Pr, n-Bu)) by reaction with HCo(CO)4 and Na[Co(CO)4], respectively. Compounds R31MCo(CO)4 with R1 = PhCH2, R21M[Co(CO)4]2 R.1 = PhCH2, were prepared both by methods A and B, while (R3O)4-n Ti[Co(Co)4]n (n = 1, 2) compounds were obtained by reaction B. Several tertiary phosphine and phosphite derivatives of the former two types were obtained by substitution of a carbonyl group by PR34 ligand or by A type reaction of HCo(CO)3(PR34 with R41M compounds.
