 Title    -Chloro-and l-Hydroxyphospholene-l-stilfides l-Chlorophospholene-l-sulfi.de Isomers, 1-Hydroxyphospholene-l-sulfide Isomers  
 Abstract    A mixture of the two isomers of 1-chlorophospholene-l-oxide, obtained by a one-step, high-yield procedure reported previously 1 , upon reaction with P4S10 was converted to a mixture of the two isomers of 1-chlorophospholene-l-sulfide which may be separated by spinning-band distillation. The thus obtained isomerically pure 1-chlorophospholene-1-sulfides were hydrolyzed to the corresponding 1-hydroxyphospholene-l-sulfides. These, as well as the precursor chloro compounds, were characterized by iH, 13 C, and 31 P NMR, mass spectrometry, and IR.

 Title    Die P207-Schwingungen in Thiamin- Diphosphat The P2O7 Vibrations in Thiamine Diphosphate  
 Abstract    The infrared P2O7 and COP vibrations of thiamine diphosphate tetrahydrate have been assigned by comparison with related species. Thiamin-Diphosphat (TDP), auch als Cocarboxy-lase bekannt, ist ein biochemisch wichtiges Coenzym in enzymatischen Systemen, welche die Deearboxy-lierung von a-Ketosäuren und die Übertragung von Aldehyd-oder Acyl-Gruppen katalysieren [1, 2], Diese Reaktionen benötigen ein zweiwertiges Metall-Ion als Kofaktor [1, 3], so daß den Untersuchungen von Metall-TDP-Wechselwirkungen besondere Be-deutung zukommt [2, 4], wobei die IR-Spektro-skopie sicherlich ein wertvolles Hilfsmittel darstellt. Die Durchsicht der einschlägigen Literatur zeigte, daß bisher noch keine vollständige IR-spektro-skopische Untersuchung von TDP durchgeführt wurde. Da die Diphosphat-Gruppe als potentielle Koordinationsstelle für die zweiwertigen Metall-ionen in Frage kommt [2, 4] und um zukünftige Untersuchungen von Me(II)/TDP-Systemen einzu-leiten, haben wir zunächst das Schwingungsspek-trum dieser Gruppierung näher untersucht. Diese Arbeit ist aber auch vom Standpunkt der spektro-skopischen Eigenschaften der Diphosphat-Ester von Interesse, da es bisher noch sehr wenig Information über solche Verbindungen gibt [5-7]. Wir haben daher Thiamin-Diphosphat-Tetra-hydrat IR-spektroskopisch untersucht und die P2O7-und C-O-P-Banden durch Vergleich mit dem Spektrum von reinem Thiamin identifiziert. Die Ergebnisse sind zusammen mit der getroffenen Zu-ordnung der Tabelle zu entnehmen. Mit (*) be-zeichnete Banden überlagern sich manchmal mit Absorptionen des reinen Thiamins, so daß es in einigen Fällen schwierig ist, ihre Lage genau fest-zulegen.

 Title    IR-und NMR-spektroskopische Untersuchungen an Rubazonsäuren 1 . Ein ungewöhnliches Achtring-Protonenchelat mit Doppelminimumpotential IR and NMR Spectroscopic Studies on Rubazonic Acids 1 . An Unusual Eight-Membered Ring Proton Chelate with Double Minimum Potential  
 Abstract    The IR and NMR spectra of rubazonic acids 1 and 2 show that these compounds form only OH tautomers in nonpolar solvents and in the crystalline state. They are stabilized by a strong intramolecular hydrogen bond in an eight-membered ring. The IR and NMR spectra show that they exhibit a symmetrical structure. The hydrogen bond has a double minimum potential. Alteration of the symmetry of substitution in 1-and 1'-positions markedly influences the signal of the OH proton. This symmetry effect is discussed. Rubazonsäure 2 (la) und ihre Derivate (lb-r) liegen in aprotischen Lösungsmitteln geringer Polarität und im Kristall als OH-Tautomere in der Z-s-cis-Form mit einer sehr starken intramolekula-ren Wasserst off brücke vor 3 . Das gleiche gilt für die strukturanalogen Verbindungen 2a-h 4 . Wegen der großen Ähnlichkeit ihrer physikahschen und chemi-schen Eigenschaften sollen die beiden Substanz-klassen im folgenden als C-und N-Rubazonsäuren bezeichnet werden.

 Title    IR Absorption of A1C1 and AlBr in Solid Noble Gases  
 Abstract    The vibrational frequency of A1 35 C1 in solid neon and argon has been measured to be 470 cm-i and 455 cm-1 . The 3 5C1/ 37 C1 isotopic splitting is 5.4 ± 0.2 cm -1 in argon matrix. The IR absorption of AlBr has been recorded in neon, argon and nitrogen matrices (370, 357, 349 cm" 1). In solid argon the frequency shift due to 81 Br/ 79 Br isotopes could be re-solved (0.95 ±0.2 cm" 1). The fundamental v3 of monomeric AlBr3 is observed at 508.4 cm -1 in an argon matrix.

 Title    Darstellung und Eigenschaften von und Reaktionen mit metallhaltigen Heterocyclen, I Metallorganische Komplexe von Mangan und Rhenium mit zwei funktionellen Zentren Preparation and Properties of and Reactions with Organometallic Heterocycles, I Organometallic Complexes of Manganese and Rhenium with two Functional Centres  
 Abstract    The binuclear anions Na2[(0C)4MP(0)R2]2 (2a, a', b, b') [M = Mn: R = CH3 (a), C6H5 (a'); M = Re: R = CH3 (b), CßHs (b')] can be obtained quantitatively by reduction of the phosphinic acid complexes (OC)4BrMP(OH)R2 (la, a', b, b') with sodium amalgam in ether. While the manganate anions 2 a, a' can be transformed with excess sodium into the mononuclear salts Na2[(0C)4MnP(0)R2] (3 a, a'), with two nucleophilic centres, the corresponding anions 2 b, b' eliminate CO to give sparingly soluble species. From 3 a, a' and dimethylsulphate the doubly methylated compounds CH3Mn(CO)4P(OCH3)R2 (4a, a') are obtained. The rhenium derivatives CH3Re(CO)4P(OCH3)R2 (4b, b') are formed only in very poor yields from 2 b, b' and dimethylsulphate under reductive conditions. The IR, *H NMR, and mass spectra are discussed.

 Title    Darstellung, Kristallstruktur und Infrarotspektrum von [MONC13 * P0C13]4 Preparation, Crystal Structure and Infrared Spectrum of [MONC13 * P0C13]4  
 Abstract    [MoNCl3 • P0C13]4 is prepared both by the reaction of MoNCl3 with POCl3 as well as by the reaction of M0CI5 with NC13 in the presence of P0C13. [MONC13 • P0C13]4 crystallizes in the monoclinic space group P2i/c with 2 tetrameric molecules in the unit cell. The crystal structure was solved by X-ray diffraction methods (R — 0.033, 1821 observed reflections). The structure consists of planar and almost square Mo4N4-eight-membered rings with alternating Mo-N bond lengths. The distorted octahedral environment of the molybdenum atoms is completed by three terminal Cl-ligands and by the oxygen atom of a POCl3 molecule, which is coordinated trans to the Mo = N triple bond. The IR spectrum is discussed with respect to the vibrational spectra of the isoelectronic niobium complex [NbOCl3 • P0C13]4.

Etherical solutions of la-c with molecular oxygen easily can be transformed into the dioxides [RC(0)P(0)(Ph)CH2-]2 (2a-c). In contrast to the monofunctional acyl(diaryl)phosphane oxides 2 a-c do not react with water at 25 °C. The 31 P, 19 F, iH NMR and IR spectra of the new compounds 1, 2 a-c are discussed.

 Abstract    Tris-tert-butylorthovanadate VO(OC4H9)3 undergoes reaction with monocarboxylic acids to yield monomeric VO(OC4H9)(RCOO)2; no VO(OC4H9)2(RCOO) or VO(RCOO)3 could be isolated from the reaction mixture. Polymeric dioxovanadium(V)-monocarbox-ylates(V02RC00) n are formed by thermolysis or partial hydrolysis of VO(ÖC4H9)(RCOO)2; the reaction mechanism is studied and discussed. Syntheses of Ba[V02(CH3C00)3], Ba[V02(C2H5C00)3] and N(C4H9)4[V408Br(CH3C00)4] are described. All compounds obtained are characterized by IR and X H NMR spectroscopy as well as by chemical reactions. The carboxyl groups are mostly acting as bidentate ligands.

 Title    Darstellung, IR-Spektrum und Kristallstruktur von [WNCI3 P0C13]4 2 POCI3 Preparation, IR Spectra and Crystal Structure of [WNCI3 * P0C13]4 * 2 P0C13  
 Abstract    Tungsten nitride chloride-POCl3 solvate, [WNC13 • P0C13]4 • 2 POCl3 is prepared by the reaction of WNCI3 with excess POCI3. With equimolar amounts of POCI3 in dichloro-methane suspension the complex [WNCI3 • P0C13]4 • 2 CH2CI2 is formed, which is easily decomposed leaving pure [WNCI3 • POCl3]4. The IR spectra of these complexes were recorded and assigned. A new preparative route to WNCI3 from tungsten hexachloride and iodine azide is described. [WNCI3 • P0C13]4 • 2 POCl3 crystallizes in the triclinic space group P 1 with two tetrameric units per unit cell. The crystal structure was solved by X-ray diffraction methods (Ä = 0,087; 3085 observed reflexions). The structure consists of planar and almost square W4N4-eight-membered rings with alternating W-N bond lengths. The distorted octahedral environment of the tungsten atoms is completed by three terminal Cl-ligands and by the oxygen atom of a POCI3 molecule, which is co-ordinated trans to the W = N triple bond. The two additional POCI3 molecules are weakly linked to two of the four POCI3 solvate molecules, giving rise to an increase of the W-0 bond lengths to these donor groups.

 Title    Borchelate und Bormetallchelate, VI [1] Zur Bildung von Borchelaten aromatischer Azoverbindungen  
 Abstract    Bidentate chelate reagents incorporating a suitable group (e.g. OH, NH2) in ortho position to the azo-group react with diphenylboronic acid anhydride or boron trihalides (BF3, BCI3) resulting in the BR2-six membered ring-chelates of types 1 and 2. The products of the reaction of tridentate chelate reagents with phenylboronic acid or boron trifluoride at elevated temperature are BR-chelates with two six membered rings (types 3 and 4). The conditions of the formation of the bicyclic chelates 5 and 6 depend on the position of the substituents of the chelate reagents. The incorporation of only one BR2 group is possible if the order of the substituents in 2,2'-dihydroxyazobenzenes is not symmetrical (chelates of the type 7). Structural isomers of boron chelates of the types 5, 6 or 7 with Na/N/S isomerism have not yet been observed. The identification of the structures of the above-mentioned complexes was achieved by means of iH, n B and 19 F NMR and IR spectroscopy. For mass spectrometric analysis see ref. [2]. Einführung Azomethine des Salicylaldehyds sind mit Bor-verbindungen leicht zu Chelaten umzusetzen [3-5]. Die ähnlich strukturierten Azo-Chelate sind da-gegen kaum [6] beschrieben worden. Folgende Aspekte führten zu den Synthesen der Borchelate: In den Chelaten 1^1 ist das Bor an dasjenige N-Atom der Azogruppe gebunden, dessen Koordination zu einem (Typ I und 2) oder zwei Chelat-6-Ringen (3 und 4) führt. Im Gegensatz zu 1-4 sind bei 5-7 die Bindungsverhältnisse der ko-ordinativen B-N-Bindung unklar. Von besonderem Interesse waren die Umsetzungen mit unsym-metrisch substituierten 2.2'-Dihydroxyazobenzolen, da die Bildung strukturisomerer Chelate (Na/N^-Isomerie) erwartet werden konnte. Ein weiterer Aspekt war die Farbvertiefung bei der Chelatbildung, die quantitative Bestimmungen

 Title    Koordinationschemie ambivalenter Liganden, VIII 1 Synthese und Reaktivität ionischer und kovalenter Sulfinato-Komplexe von Tetraorganyl-VB-Elementen des Typs R4'E02SR Synthesis and Reactivity of Ionic and Covalent Sulfinato Complexes of Tetraorganyl-VB-Elements of the Type R4'E02SR  
 Abstract    The synthesis of the sulfinato derivatives 1-7 of pentavalent YB-elements follows equation (2). These compounds differ significantly in their physical and chemical properties and in their structures. In between the extremes of the purely ionic tetramethylam-monium sulfinates la-c and the typically covalent and pentacoordinated tetraorganyl-sulfinato-O-stiboranes 6-7, there are the hexa-or pentavalent compounds of phosphorus and arsenic 2 and 4 or 3 and 5 with sulfinato-0,0' or sulftnato-0 linkage, which dissociate readily into their ionic components. 1 a-c are suitable for the synthesis of sulfones according to equation (3). All of the methylsulfinato derivatives can be easily transformed (equation (4)) into the corresponding sulfonates by air oxidation. Only the tetraphenylsulfinato-O-stiboranes 7 a-c show S02-elimination forming pentaorganylstiboranes (equation (5)). IR, mass and in some cases NMR spectra are reported.

 Title    Das Verhalten von (Halogen)Acyldiphenylphosphinen gegenüber molekularem Sauerstoff in Abhängigkeit vom Acylrest Behavior of (Halogeno) Acylphosphines Towards Molecular Oxygen in Dependence of the Acyl Residue  
 Abstract    The halogenated acylphosphines RC(0)PPh2 (la-f) [R = C1CH2 (a), FCH2 (b), F2CH (c), C2F5 (d), C3F7 (e), CöFö (f)], which can be oxidized by rigorously dried oxygen to the phos-phine oxides RC(0)P(0)Ph2 (2a-f), are obtained by reaction of NaPPh2 with the acyl chlorides RC(0)C1. From 2a-f and stoichiometric amounts of water the alcohols RC[Ph2P(0)]20H (3a-f) are formed. While 3c-f are isomerized into the phosphinates RC[Ph2P(0)][0P(0)Ph2]H (4c-f), the alcohols 3a, b are stable. The hydrolytic and thermal behavior of the phosphine oxides 2 and the alcohols 3 are discussed regarding the nature of the acyl residue.

 Title    Metal(II) Complexes of 1,2,5-Oxadiazole  
 Abstract    A series of new coordination compounds is reported with 1,2,5-oxadiazole (ODZ) as the ligand, viz. [M(ODZ)3](SbCl 6)2 with M = Mg(II), Mn(U), Fe(II), Co(II), Ni(II), and Zn(II). The metal ions are in a regular octahedral environment of six nitrogen atoms. The ligands function as bidentate bridges between the metal ions.
