Über neue Cyano-nitrosylmanganate und Isonitril-nitrosyl-Komplexe des Mangans/On New Cyano Nitrosyl Manganates and Isonitrile Nitrosyl Complexes of Manganese
Authors: Moll Matthias , Behrens Helmut , Trümmer Karl-Heinz , Merbach Peter 
Published: February 2015

Abstract
The anionic cyano nitrosyl manganates [Mn(NO)(CO)3CN] - and [Mn(NO)3CN]- are formed by the reactions of Mn(NO)(CO)4 and Mn(NO)3CO with NaN(SiMe3)2. The alkylation of these anions with [R3O]BF4 (R = Me, Et) leads to the corresponding isonitrile complexes Mn(NO)(CO)3CNR and Mn(NO)3CNR. IR, mass and 13C NMR spectra indicate trigonal-bipyramidal coordination for nitrosyl tricarbonyl derivatives, with three CO ligands in facial positions and NO in the equatorial plane. Based on the temperature dependent 13C NMR spectra of Mn(NO)(CO)3CNR and Mn(NO)(CO)4 the fluctional behaviour of these compounds could be demonstrated with ⊿G+ values of 48 kJ/mol or less for the CO exchange.
Beiträge zur Chemie des Phosphors, 125/Synthese und Struktur der Triorganyl-nonaphosphane(3) P9(i-Pr)3 und P9 (t-Bu)3

Published: February 2015

Abstract
The triorganyl-nonaphosphanes(3) P9(i-Pr)3 (1) and P9(t-Bu)3 (2) have been obtained by reacting (i-PrP)4 with PCl3 and by dehalogenating a mixture of t-BuPCl2 and PCl3 with magnesium, respectively. In the case of P9Et3 (3) and P9Me3 (4) the latter reaction may be modified by using the organyl-cyclophosphanes (PR)n instead of RPCl2. P7R3 as well as other polycyclic organylphosphanes are formed as by-products. 1 could be isolated in pure form and 2 has been concentrated in the product mixture. According to their 31P{1H}-NMR spectra 1-4 possess a P9 skeleton analogous to that of the hydrocarbon deltacyclane. 1 and 2 are formed as mixtures of two configurational isomers, which differ in the spatial arrangements of the substituent on P5. The results clearly indicate, that the corresponding phosphorus hydride P9H3 has the same structure and is a tetracyclo[4.3.0.02,4.03,7]nonaphosphane.
Darstellung von trans-[PtCl4Br2] 2 -und [PtCl5Br] 2- durch oxidative Addition an [PtCl4]2-/Preparation of trans-[PtCl4Br2] 2--and [PtCl5Br] 2 -by Oxidative Addition to [PtCl4]2-
Authors: Preetz W. , Rimkus G. 
Published: February 2015

Abstract
The oxidative addition of Br2 to [PtCl4]2-in HBr yields almost pure trans-[PtCl4Br2]2-, in HCl nearly pure [PtCl5Br]2-, and in CH2Cl2 by a quantitative and stereospecific reaction completely pure trans-[PtCl4Br2]2-. This is confirmed by ion exchange chromatography on diethylaminoethyl cellulose and by analysis of the vibrational spectra in comparison with the IR and Raman spectra of the well-known species of the series [PtClnBr6-n]2- , n = 0-6. The literature concerning trans-[PtCl4Br2]2- and other mixed ligand complexes is critically discussed.

Published: February 2015

Abstract
The addition of CF3SCl (2) to the fluorinated nitriles RfCN[Rf = CF3 (3), NSF2 (4), NSOF2 (5)] leads to N-perfluoromethanesulphenyl-formylimidoylchlorides CF3S-N = C(Cl)Rƒ (6, 11, 12). From the reactions of SCl2 (1) with (3) and (5), which yielded the N-sulphenyl-chlorides ClS-N = C(Cl)-Rƒ(7, 13), it proved possible also to isolate the oxidation product [CF3CCl2NSCl2 (8)] and an oligomer of the nitrile [(NCNSOF2)3 (14)]. Dechlorination of 7 with Hg gives the corresponding di-and tri-sulphides (CF3C(Cl) = N-)2Sx; (9, 10, x =2, 3). Crystals of (14) are triclinic with a = 1133.6(5), b = 1332.6(5), c = 1715.1(8) pm, α = 109.31(3), β = 105.30(3), γ = 97.84(3)° at 170 K, Z = 8, space group P1̄. The structure was refined to R = 0.028 for 8290 diffractometer data with F > 4σ (F). The four crystallographically independent molecules adopt similar unsymmetrical conformations.

Published: February 2015

Abstract
The preparation of bis-hydroxophthalocyaninatoferrate(III) and of some of the bis-alkoxo-analogues is described. In the presence of a small excess of OR -(R = H, CH3, C2H5, (CH3)2CH, (CH3)3C) these complexes are stable in most common non-polar solvents and can be isolated as analytically pure bis-triphenylphosphiniminium-(PNP)-salts. Solutions of these complexes react immediately with water and acids. Thus hydrolysis is an easy way to prepare μ-oxo-bis-phthalocyaninatoiron(III). The reaction with mineral acids HX (X = F, Cl, Br, I) precipitates the pure pentacoordinated halogenophthalocyaninatoiron-(III). The electronic absorption spectra have been measured. Besides the typical inner-ligand π-π*-transitions additional bands are observed at ~11,5kK (CT1) and ~20kK (CT 2). These bands are of medium intensity only for FeXPc(-2) (X = Cl, Br, I) especially in the solid state spectra and are probably associated with ligand-to-metal-charge-transfer(CT)-transitions mainly of the Pc → Fe-type but partially mixed with X→Fe. CT 1 and CT2 are assigned to (a1)π → (e,a1)d respectively. This is confirmed by the resonance Raman spectra. On excitation within the range of the CT 2 electronic transition some in-plane stretching-(1595 and 1550 cm -1) and out-of-plane deformation vibrations (350 and 290 cm -1) of the macrocycle as well as the Fe-X-stretching vibrations are resonance Raman enhanced. Combination bands of Fe-X-with Pc-vibrations give strong evidence for coordination of the halide to an axial position of the iron centre. As expected for C4V point symmetry the Fe-X vibrations are IR active, too (ν(Fe-X) for X = F: 475; Cl: 303; Br: 221; I: 193 cm -1). The Fe-O stretching vibration (a1g) is only observed in the resonance Raman spectrum of PNP[Fe(OH)2Pc(-2)] at 495 cm -1 . As a consequence of the strong antiferromagnetic coupling the IR and resonance Raman spectra of (FePc(-2))2O resemble those of closed shell ions. The IR absorption at 822 cm-1 is assigned to the anti-symmetric (a2u) (Fe-O-Fe) deformation mode.
Azaborolinyl-Komplexe, IX Die Kristall- und Molekülstrukturen von zwei Isomeren des Bis(1-tert-butyl-2-methyl-η-1.2-azaborolinyl)cobalts/Azaborolinyl Complexes, IX The Crystal and Molecular Structures of Two Isomers of Bis(1-tert-butyl-2-methyl-η-1,2-azaborolinyl)cobalt
Authors: Schmid Günter , Boese Roland 
Published: February 2015

Abstract
The crystal and molecular structures of two isomers of bis(1-tert-butyl-2-methyl-η-1,2-azaborolinyl)cobalt have been determined by single-crystal X-ray diffraction methods. Isomer 1 shows a clockwise, isomer 2 an anti-clockwise conformation of the azaborolinyl rings. In both compounds the azaborolinyl rings have staggered orientations with opposite positions of the tert-butyl groups. The rings in 1 and 2 are slipped so that the three ring carbon atoms are closer to the cobalt atom than the BN groups. The staggered orientation of the ligands in 2 is probably due to a packing effect, as in similar sandwich complexes the anti-clockwise conformers show eclipsed orientation.

The crystal structure of orthorhombic PbSO3 (Pnma, Z = 4, a = 790.3(1), b = 548.8(1), c = 680.2(1) pm) has been determined using single crystal X-ray diffraction data (final R for 663 reflections with I ≥ 2σ(I) = 0.052). The parameters of the atoms in the asymmetric unit are: Pb(4c) 0.68444(8), 0.25, 0.36072(8); S(4c) 0.5362(5), 0.25, 0.8470(5); O1(4c) 0.686(2), 0.25, 0.981(2); O2(8d) 0.563(1), 0.471(2), 0.712(1). The sulfite ion has S-O distances of 149.4(7) and 153.7(5) (twice) pm. The Pb-O distances of the edge-connected Pb-O7 polyhedra (distorted mono-capped trigonal prism) range from 253.4(5) to 284.8(5) pm. The structure is closely related to that of PbSO4.

Authors: Tebbe Karl-Friedrich , Fröhlich Roland 
Published: February 2015

Abstract
The new compound Rb[I(ICN)2] can be prepared in aqueous solution by simple addition of two mole equivalents of ICN to one formula unit Rbl. The solid is isotypic with Cs[I(ICN)2] and crystallizes in the orthorhombic space group Pmmn with a = 16.246 Å, b = 6.795 Å, c = 4.397 Å and Z = 2. The crystal structure has been solved from diffractometer data and refined to R = 0.035 for 313 observed reflections.
The structure may be interpreted as a layer-like package of Rb+ cations and pentahalideanalogous anions [I(ICN2]-. The anionic groups are angular with symmetry mm 2 and φ ( I-I-- I ) = 128.69°, φ(I--I-C) = 175.5°, φ=(I-C-N) = 177°, d(I--I) = 3.271 Å, d(I-C) = 2.11 A, d(C-N) = 1.13 A. The cation is surrounded by a distorted cube of iodine atoms with a minimum distance d(Rb-I) = 3.775 Å.
Some additional results on the reactions of alkali halides and halogenocyans in different solvents are mentioned and compared with those described elsewhere.

Abstract
The trimethylsilylalkyl acetoacetates 1 b and 2 b as well as their carba analogues 1 a and 2 a have been reduced microbiologically by Kloeckera corticis (ATCC 20109), leading to the corresponding ( + )-3(S)-hydroxybutanoates 3b, 4b, 3a, and 4a. The enantiomeric purity was found to be 80% (3a, 3b, 4b) and 65% (4a), respectively. The reduction of lb and 2b is - to our knowledge - the first example for a controlled microbiological transformation of organosilicon substrates.

Mößbauer-und Röntgenphotoelektronen-spektroskopische Untersuchungen an Berlinerblau-Analoga des Typs Fe[MB(CN)6] / Mößbauer and X-Ray Photoelectron Spectroscopic Studies on Prussian Blue Analogs of the Type Fe[MB(CN)6]
Authors: Inoue Hidenari , Fluck Ekkehard 
Published: February 2015

Abstract
Prussian Blue analogs of the type Fe[MB(CN)6] (MB = Pd and Pt) crystallize in the face-centered cubic system: space group Fm3m-Oh
5, Z = 4. Magnetochemical and Mößbauer spectroscopic measurements have revealed that nitrogen-coordinated iron(II) ions and carbon-coordinated MB(IV) ions are in the high spin state and in the low spin state, respectively, in the temperature range 4.2 to 300 K. Upon the formation of Fe[MB(CN)6] from K2[MB(CN)6], the binding energies of N 1s, Pd 3d5/2 and Pt 4f7/2 increase while the C 1 s binding energy decreases. This tendency could be interpreted in terms of the inductive effect of iron(II) ions attached to the nitrogen end of cyanide ligands.

Authors: Lindner Ekkehard , Tamoutsidis Efstathios 
Published: February 2015

Abstract
The unsaturated acylphosphanes RC(O)PPh2 (4a, b') [R = Ph-CH = CH (a), C3H4N2(Cl)-C(Ph) = CH (b')] are obtained by reaction of RC(O)Cl (3a, b') with (CH3)3SiPPh2. The preparation of 3b' is possible by addition of imidazole to the triple bond of Ph-C=C-C(O)OC2H5 and subsequent hydrolysis of RC(O)OC2H5 (lb) [R = C3H3N2-C(Ph) = CH (b)] and chlorination of RCO2H (2b'). From 4a and imidazole the imidazolide Ph2P(Ph)CH-CH2-C(O)-N2C3H3 (5) is formed which can be oxidized to give Ph2(O)P(Ph)CH-CH2-C(O)-N2C3H3 (6). 4a is coordinated in two different ways to transition metals. A 1:1 molar ratio of 4 a and LnMnTHF [LnMn = (η5-C5H5)Mn(CO)2] yields the P-coordinated complex RC(O)P(Ph2)-MnLn (7a). Excess of LnMn·THF results in the formation of P- and η2-coordinated LnMn-P(Ph2)C(O)(η2-C2H2Ph)MnLn (8a). In the presence of HP(O)Ph2, 4a is oxidized with molecular oxygen to give the phosphorylated alcohol RC[P(O)Ph2]2OH (9a). Via the oxide 10 a and the enol ether Ph2(O)P-CHPh-CH = C(OCH3)P(O)Ph2 (11a) the ester Ph2(O)P-CHPh-CH = C[OC(O)R]P(O)Ph2 (12 a) can be isolated from the Arbusov reaction of 3a and CH3OPPh2.

Abstract
2,2,2-Trimethoxy-3,3-bis(trifluoromethyl)-2,2-dihydro-1,4,2-oxazaphosphol-4-enes on thermolysis undergo a 1,3-dipolar cycloreversion reaction with formation of bis(trifluoro-methyl) substituted nitrile ylides. Trapping reactions of the 1,3-dipolar species with α,β-unsaturated carboxylic acid esters and nitriles are described. 2-Aryl-3-carbethoxy-5,5-bis(trifluoromethyl)-1-pyrrolines obtained undergo an uncatalyzed autoxidation pro-cess to give 2-aryl-3-carbethoxy-3-hydroxy-5,5-bis(trifluoromethyl)-1-pyrrolines. 5,5-Di-fluoro-4-trifluoromethyl-2-oxazolines and 5-fluoro-4-trifluoromethyl-oxazoles formed as by-products indicate that the thermal induced [3+2]-cycloreversion reaction of 2,2,2-tri-methoxy-3,3-bis(trifluoromethyl)-2,2-dihydro-1,4,2-oxazaphosphol-4-enes is most likely a stepwise process.

Abstract
Solutions of mono-and bis-N-methylcarbamoyl phosphates in non-aqueous solvents [e.g. acetonitrile, dimethyl formamide, chloroform) and, surprisingly, even in water are readily obtained by the reaction of methyl isocyanate with the solution of an appropriate mono-or dihydrogenphosphate. The course of the reactions and the limited stability of N-methylcarbamoyl phosphate ions in solutions can be monitored through 31P NMR measurements. Various types of compounds, including a coordination compound of cobalt could be isolated in crystalline form: [Et3NH]HX, KHX, NH4HX, Na2X · H2O, MgX · 4 H2O, CaX · H20, SrX · 2 H2O, BaX · H2O, ZnX · 5 H2O, CdX · 2 H2O, [(NH3)5CoX]ClO4, [Et3NH]Y, AgY · MeCN, X = MeNHC(O)OPO3, Y = [MeNHC(O)O]2PO2.
