Structural Change of a Line ar Polyether upon Complex Formation. 1.11-Bis(2-acetylaminophenoxy)-3.6.9-trioxaundecane and its KSCN Complexa
Authors: Suh Il-Hwan , Weber Gabriela , Kaftory Menachem , Saenger Wolfram , Siegerd Heinz , Vögtled Fritz 
Published: February 2015

The title compound (1) was crystallized as free ligand and as its (1 · KSCN)2 · H2O complex. Crystallographic data are, for the former: space group C 2/c, a = 31.110(9), b = 4.608(4), c = 17.188(6) Å, β = 105.27(8)°, Z = 2, Dm = 1.25 gem-3; for the latter: space group P21, a = 11.044(3), b = 18.310(4), c = 14.485(4) Å, β = 97.49(2)°, Z = 4, Dm = 1.27 gem-3. Crystal structures were solved by direct methods using X-ray diffraktometer data and least squares refinements converged at 10.8% for 1 and at 7.6% for (1 · KSCN)2 · H2O.
The free ligand (1) is S-shaped and, upon K+-complexation, changes signs of some gauche O-C-C-O torsion angles while C-C-O-C angles remain trans. In (1 · KSCN)2 · H2O, there are two complex molecules 1 A · KSCN · H2O (I) and 1 B · KSCN (II). The ligands are wrapped circularly around K+ and coordinated with only four of the five polyether oxygens. K+ interacts further with H2O in (I) and with N of SCN- in II and, in both complexes, with acetylamino oxygen of adjacent 1. The latter interaction leads to polymeric structures not observed previously for similar complexes.

SO2 -Insertion an phosphinsubstituierten und anionischen Triorganozinn-Komplexen des Chroms, Molybdäns und Wolframs / Reactivity of Organometallic Complexes Containing Tin-Metal Bonds, IV [1]. SO2 Insertion into Phosphine Substituted and Anionic Triorganotin Complexes of Chromium, Molybdenum and Tungsten
Authors: Kunze Udo , Sastrawan S. Budhi 
Published: February 2015

Abstract
The trans phosphane and phosphite substituted organotin complexes of molybdenum 1-4 are prepared by thermolysis or photolysis of the tricarbonyl parent compounds. The phosphane complexes 1 and 2 react readily with liquid sulfur dioxide by absorption of 1-3 moles of SO2 depending on temperature. IR and NMR spectra indicate cleavage of tin-carbon bonds only yielding insertion products of the sulfinato-O type 1a-c and 2a-c. The phosphite complexes 3, 4 are less reactive and yield a di-insertion 3a and a mono-insertion compound 4a. The anionic triphenyltin derivatives of chromium, molybdenum and tungsten 5-7 undergo facile cleavage of 1 (Cr) or 3 (Mo, W) tin-phenyl bonds. The course of SO2 insertion into 1-7 reveals a distinct activation of the Sn-C bond in organotin transition metal complexes by substitution with stronger donor molecules or reduction to anionic species.
Beiträge zur Chemie des Phosphors, 96 [1] Darstellung und 31P-Kernresonanzspektrum von isotopen-substituiertem Trilithium-heptaphosphid, 6Li3P7 / Contributions to the Chemistry of Phosphorus, 96 [1] Preparation and 31P NMR Spectrum of Isotopicly Substituted Trilithiumheptaphosphide, 6Li3P7
Authors: Baudler Marianne , Pontzen Thomas , Hahn Josef , Ternberger Hans , Faber Wolfgang 
Published: February 2015

Abstract
The P7-skeleton of trilithiumheptaphosphide, Li3P7 (1), was proved to possess the earlier reported tricyclic structure [2] by complete analysis of the 31P NMR spectrum of 6Li3P7 observed at - 60 °C. The 6Li isotopic substitution was carried out to avoid the line broadening caused by the large quadrupole moment of the 7Li isotope. The unambiguous elucidation of the Li3P7 structure confirmed that the exchange process which causes all P atoms to become equivalent above room temperature is analogous to that in bullvalene. A comparison of the chemical shifts with those of (Me3Si)3P7 leads to the result that the P7-skeleton in Li3P7 is noticeably compressed along its threefold axis, thus indicating a predominant ionic character.
Vereinfachte Synthese und Reaktionen von Selenocarbonyldifluorid / A Simplified Synthesis and Reactions of Selenocarbonyldifluorid
Authors: Darmadi Alexius , Haas Alois , Koch Bernd 
Published: February 2015

Abstract
SeCF2 is prepared on a preparative scale reacting AII3 with Hg(SeCF3)2 in octamethyl-cyclotetrasiloxane. It adds MF [M = Cs, Tl, [(CH3)4N] and Ag] to form MSeCF3. AgSeCF3 was also synthesized from AgF and B(SeCF3)3. Under the influence of sunlight SeCF2 dissolved in CFCI3 dimerizes quantitatively to 2,2,4,4-tetrafluoro-1,3-diselenetane, which above 360 °C pyrolyses to the monomer. The cyclic dimer reacts with B(SeCF3)3 to give (CF3Se)2CSe. The reaction of AgSeCF3 with CFnCl3-nSCl leads to CF3SeSCFnCl3-n (n = 1, 2, 3). IR, NMR and mass spectra of the newly prepared compounds were presented.

Abstract
The electrolysis of P4/HSO3F mixtures does not yield detectable phosphorus-polyatomic cations; the intense coloration of the electrolyte is due to the known sulfur polyatomic cations originating from decomposition of HSO3F.

Abstract
The reactions of tricarbonyl nitrosyl cobalt with tri-tert-butylphosphine, di(tert-butyl)-trimethylsilyl-, -germyl-, -stannylphosphine, tert-butyl-bis(trimethylsilyl)-, -(germyl)-, -(stannyl)phosphine, as well as with tris(trimethylsilyl)-, -(germyl)-, and -(stannyl-phosphine result in the elimination of one CO-ligand and the formation of corresponding dicarbonyl-nitrosyl-organometal phosphine cobalt complexes. The NMR spectra of the products are reported and discussed.
Dodecamethyl Bisimidotriphosphoramide (TRIPA) A Tridentate Ligand, Part II [1]
Authors: Lapidaire Johannes C. P. M. , Groeneveld Willem L. 
Published: February 2015

Abstract
In this article we describe the synthesis of TRIPA, dodecamethyl bisimidotriphosphoramide (C12H36N7O3P3) and of its complexes with various lanthanide-nitrates. Five types of complexes have been isolated according to the compositions, X-ray diffraction patterns and IR spectra.
1. M(N03)3(TRIPA)3(acetone) M = La, Pr, Nd,
2. M(N03)3(TRIPA) M = Y,
3. M(N03)3(TRIPA)2(nitromethane) M = Er, Y,
4. M(N03)3(TRIPA)2(acetone) M = Sm, Gd, Dy, Er, Y (type I),
5. M(N03)3(TRIPA)2(acetone) M = Y (type II).
The yttrium complexes, type I and II, are isomeric. IR spectra are given together with the NMR spectra. It is concluded that in all complexes the three TRIPA oxygens are coordinated, except in group 1. The nitrate groups in group 2 to 5 are involved in the coordination, particularly in the type 2 complex, where there are bidentate nitrate groups. There seems to be a difference in the conformation of the TRIPA molecules between the free ligand, the complexes in group 1, in group 2 and in group 3, 4, 5 Hygroscopic TRIPA can be easily confused with a stable mono-hydrate, TRIPA · H2O.

Abstract
The new compounds Tb6Br7 and Er6I7 are formed from the trihalides with an excess of metal in sealed tantalum containers. X-ray structure investigations [space group C2/m; Tb6Br7 (Er6I7): a = 2057.1 (2137.5), b = 379.3 (386.9), c = 1180.0 (1231.9) pm, β = 124.59° (123.50°)] show one-dimensional regions connected by Ln-Ln bonds. The structure type can be described in terms of Ln6X12-clusters which are linked via edges of Ln6-octahedra to form double strings. The structure is derived from an FCC arrangement of halogen atoms part of which is systematically substituted by Ln6-octahedra.

Präparative und röntgenographische Untersuchungen über Cäsium-Silber-Gold(III)-Chlorid/Preparation and X-ray Investigations of Cesium Silver Gold(III) Chloride
Authors: Berthold Hans Joachim , Ludwig Wolfgang 
Published: February 2015

Cesium silver gold(III) chloride has been prepared from hydrochloric acid solutions. The composition of the preparations is variable and depends on the ratio [Au(III)]/[Ag(I)] in solution. It corresponds to the formula Cs2Ag1-xAu1+x/3Cl6. In the range 0 ≤ x ≤ 0,64 six crystallographically different phases have been observed. Above x = 0,42 a cubic phase is obtained. The stoichiometric compound Cs2AgAuCl6 is obtained only from solutions with [Au(III)]/[Ag(I)] < 1.
Reports in the literature which claim the stoichiometric compound Cs2AgAuCl6 to exist in a cubic and in a tetragonal form cannot be confirmed. Cs2AgAuCl6 crystallizes orthorhombically with the lattice constants a = 15,21 Å, b = 15,16 Å and c = 10,32 Å (Z = 8).

Abstract
The Compounds [(PMe3)2RhCl]2 and [Rh(PMe3)4]Cl react with indenyllithium to give C9H7Rh(PMe3)2. The strong Lewis basicity of this complex is demonstrated by its reactions with NH4PF6, MeI and MeCOCl which lead to the cations [C9H7RhR(PMe3)2]+ (R = H, Me, COMe). The hydrido complex [C9H7RhH(PMe3)2]PF6 reacts with 1,5-C8H12, CO and PMe3 by complete displacement of indene to give [Rh(PMe3)2(C8H12)]PF6, [Rh(PMe3)2(CO)3]PF6 and [Rh(PMe3)4]PF6. Reaction of [C9H7RhH(PMe3)2]PF6 with C2H4 yields an equilibrium mixture containing the cationic tris(ethylene) complex [Rh(PMe3)2(C2H4)3]+ .

Solubilization of Methylene Blue in Reversed Micelles, Effect of Water
Authors: Miyoshi Norio , Tomita Giiti 
Published: February 2015

Abstract
The solubilization of methylene blue in dodecylammonium propionate reversed micelles in cyclohexane depended strongly on the solubilized water content. Methylene blue solubilized in the micelle of which head groups are not completely hydrated by bound water exhibited the new absorption bands at 495 and 270 nm, but these bands did not appear in the micelle containing free water. This dye had the absorption bands at 655 and 290 nm in the latter micelle. The solubilizing process and solubilized state of methylene blue in the reversed micelles were discussed with results obtained.
Quantitative Evaluation of the Reactivity of Alkylating Agents
Authors: Bodor Nicholas , Kaminski James J. , Worley S. D. , Gerson Steven H. 
Published: February 2015

Abstract
A sensitive and reproducible method for quantitative evaluation of the relative reactivities of alkylating agents was developed, based on competitve alkylation. The method is superior to the known colorimetric methods. The reactivities of the agents could also be correlated with the 13C chemical shifts of the α-methylene. The method was successfully applied for the ranking of "soft" alkylating agents of low reactivity.

Besides these two compounds, Teuchamaedryn A (3) and B (4) were isolated from the better fraction as well. The structure and the stereochemistry of Teuchamaedryn A, B and Teucrin E were established on the basis of spectral evidence, chemical transformation and correlation.
(η-Cyclooctatetraen)(η-cyclooctatrienyl)rhodium(I) und einige verwandte Rhodiumkomplexe / (η-Cyclooctatetraene)(η-cyclooctatrienyl)rhodium(I) and Some Related Rhodium Complexes
Authors: Stühler Hans-Otto 
Published: February 2015

Reactions of [(COD)RhCl]2 (COD = 1,5-cyclooctadiene) with n-butyllithium in THF and isoprene or 4-vinylcyclohexene lead to formation of the known complexes [(COD)Rh-(1,2-dimethylallyl)] (2) and [(COD)Rh(5-ethylcyclohexenyl)] (3), respectively. With cyclo-octatetraene three complexes are formed:
[(COD)Rh(cyclooctatrienyl)] (4), [(COD)2Rh2-μ-(cyclooctatetraene)] (6), and the title compound (cyclooctatetraene)(cyclooctatrienyl)rhodium(I) (5). It follows from 1H NMR investigations that 5 contains a 1,2,5,6-tetrahapto cyclooctatetraene whilst the cycloocta-trienyl ligand is bound in the symmetrical 3-5-trihapto form, the Rh-atom thus achieving a 16-electron configuration. In solution at -30 °C 5 is converted to a dinuclear complex 7 which apparently can be formulated as (1,2,5,6-η-cyclooctatetraene)-μ-(3-5-η: 1-2:6-7-η]-cyclooctatrienyl) (3-5-η-cyclooctatrienyl)dirhodium(Rh-Rh)

Reactions of Ferrocenyldiphenylphosphine. Effects of the Ferrocenyl Group at Phosphorus on the Course of Decomposition of Phosphonium Betaines and Vinylphosphonium Salts
Authors: Allen David W. 
Published: February 2015

Abstract
The reaction of ferrocenyldiphenylphosphine with styrene oxide in ethanol gives, as the major product, ferrocenyl(phenyl)(1,2-diphenylethyl)phosphine oxide (5, R = Ph), the result of a rearrangement involving phenyl migration from phosphorus to adjacent carbon in the decomposition of a vinylphosphonium ion arising from protonation and subsequent elimination of water from the initially-formed phosphonium betaine. A related phenyl migration occurs in the reaction of the phosphine with ethyl propiolate in wet THF. The presence of a ferrocenyl group at phosphorus in Wittig reactions of semistabilised ylides causes the expected decrease in the cis-trans ratio of the resulting alkenes, consistent with its behaviour as an electron-donating substituent.

Abstract
Tetrafluoroborate in (η5-C5H5)(OC)3MoFBF3 is easily substituted by cyclic ethers (CH2)nO (n = 2,3,4)at -30°C in CH2Cl2 to give cationic complexes[(η5-C5H5)(OC)3MoO(CH2)n]+BF4-. With dioxane mononuclear and dinuclear dioxane bridged cationic complexes have been obtained. Ring opening of oxirane in [(η5-C5H5)(OC)3MoO(CH2)2]+ occurs at low tem-peratures; in the presence of oxirane or acetone formation of dioxane or 2,2-dimethyl-1,3-dioxolane, respectively, has been observed. The dioxolane has been obtained also in high yield by direct cyclisation of oxirane and acetone using [(η5-C5H5)(OC)3Mo(acetone)]+ as catalyst.

Abstract
From the system of isomeric complex ions [Os(NCS)n(SCN)6-n]3-, 9 of 10 possible species, n = 1-6, are isolated, including for n = 2, 3, 4 the first representatives of pure geometric bond isomers. By reaction of K2[OsCl6] with aqueous KSCN solution at reflux temperature, trans(mer)-complexes, and on treatment at 60 °C exclusively cis(fac)- complexes are formed. By ion exchange chromatography on diethylaminoethyl-cellulose columns, from mixtures of pairs of geometric isomers the pure trans(mer)-compounds are enriched in front, the cis(fac)-species at the end of the zones. Characterization and assignment of the configuration of the geometric isomers is based upon the reproducible differences in the IR and Raman spectra.

Nonenzymatie Formation of Energy Rich Phosphates in the Course of Imidazole Oxidation with Fenton's Reagent
Authors: Saygin Ömer 
Published: February 2015

Abstract
Oxidation of substituted imidazoles with modified Fenton's reagent (Fe(II), ascorbic acid, EDTA and H2O2) in aqueous solution at pH 5-7 in the presence of inorganic ortho-phosphate gives high yields of an unknown bound phosphate, in the case of 2-methyl-imidazole up to 35% based on inorganic phosphate. The dependence of the yields on reaction parameters and the hydrolytic behaviour of the compound was studied. The products are unstable in alkaline medium and fairly stable in acid solution (half-life period ca. 1 h at 25 °C in 1 N perchloric acid). Similar bound phosphate was also observed using autoxidation with O2 instead of H2O2.
MNDO-Rechnungen zur unimolekularen CO-Abspaltung aus Isomeren C3H5CO+ -Ionen / MNDO Calculations on the Unimolecular CO Loss from Isomerie C3H5CO+-Ions
Authors: Frenking Gernot , Schmidt Jochen , Schwarz Helmut 
Published: February 2015

Abstract
In agreement with experimental results MNDO calculations indicate that unimolecular CO loss from the isomeric ions CH2 = CHCH2-CO+ (1), c-C3H5-CO+ (2), and CH3CH = CH-CO+ (3), gives exclusively allyl cation (4). It is shown that, whereas CO loss from 1 is a continuously endothermic process, the analogous reaction from 2 and 3 follows relatively complicated pathways. For 2, the energetically most feasible reaction involves an isomerization of 2 to 1 via the intermediate α-oxo-and β-oxocyclobutyl cations (8) and (9). This reaction sequence is 10 kcal • mol-1 lower in energy than direct CO loss from 2 coupled with isomerization of the incipient cyclopropyl cation (7) to allyl cation (4). For 3 it is shown that this ion undergoes isomerization to 2 prior to CO loss. The alternative reaction, i.e. direct CO elimination giving rise to 1-propenyl cation (11) or isomerization to 1 were 35 and 43 kcal • mol-1 higher in energy than the process 3 → 2.
