 Title    Darstellung und Eigenschaften von und Reaktionen mit metallhaltigen Heterocyclen, VII [1] Heterolytische Spaltung der Re-Re-Bindung in den Zweikern-Anionen [(OC)4ReP(R2 )0] 2 2 ~ mit Elektrophilen - ein Weg zu Heterocyclen mit Re-C-o-Bindung Preparation and Properties of, and Reactions with, Metal-Containing Heterocycles, VII [1] Heterolytic Cleavage of the Re-Re Bond in the Binuclear Anions [(0C)4ReP(R2)0]2 2_ with Electrophiles -a Pathway to Heterocycles with Re-C a Bonds  
 Abstract    The preparation of the six-membered rhenacyclohexanes (OC)4ReP(R2)OCH2C(CH3)2CH2 (la, b) [R = CH3 (a), C6H5 (b)J is accomplished by heterolytic cleavage of the Re-Re bond in the binuclear anions [(0C)4ReP(R2)0]2 2 -with strong electrophiles like the alkane-diylbis(triflate) (CH3)2C(CH2Y)2 (Y= OSO2CF3), followed by an attack of the a>-positioned carbenium-like C atom on the phosphinite oxygen of the anion. 1 a, b insert SO2 under ring I I

 Title    Konformationsuntersuchungen an benzokondensierten Achtringen Conformation Analysis of Benzo-Condensed Eight-Membered Rings  
 Abstract    The annellation of 1-4 benzene rings to carbocyclic 8-rings increases stepwise the activation barrier for the ring inversion. A drastic consequence of the steric hindrance in the transition state is the rigidity of 9,10-dihydro-tribenzo[a,c,e]cyclooctenes at room temperature. With the aid of a complete analysis of the iH NMR spectra a decision is possible between fixed C2-conformations (e.g. 8) and Cs-conformations (e.g. 9).

 Abstract    W. Zeiß et al. • (MePNMe)4S3, ein Cyclotetra(A 3 ,A 5 ,A 5 ,A 5 -phosphazan) (MePNMe)4S3, a Cyclotetra(A 3 ,A 5 ,A 5 ,A 5 -phosphazane) 31 P} Decoupling Octamethylcyclotetra(A 3 -phosphazane) (1) reacts with three mole equivalents of sulfur, added either in excess or in deficite, to give 2, the first cyclotetra(A 3 ,A 5 ,A 5 ,A 5 -phosphazane). Its crystal structure determination shows a completely unsymmetrical molecule, which does not undergo ring inversion in solution. Thus an ABMX spin system with remarkably different AM and BM coupling constants is observed in the 31 P{ 1 H} NMR spectrum. By means of selective { 31 P} decoupling, all CH3 proton signals could be assigned in the 1 H NMR spectrum.

 Title    Derivatives of cis-NPCl2(NSOCl)2 and (NPC12)2NS0C1, Part XV [1] Methyl-and Ethylamino Derivatives of (NPCl2)2NSOPh  
 Abstract    The aminolysis of (NPCl2)2NSOPh by methyl-and ethylamine in diethylether proceeds mainly via a non-geminal substitution pattern. In acetonitrile both geminal and non-geminal substitution is observed. The preparation of the derivatives is described and the iH and 31 P NMR data are discussed. The interpretation of the NMR spectra is supported by the simulation of the spectra of NPClNHMeNPCl2NSOPh.

 Abstract    Einfache Synthesen der trimethylenverknüpften Triphosphine RP[(CH2)3PPh2]2 und ihrer Vorstufen Ph2P(CH2)3P(H)R (R Ph, Me) Oligophosphine Ligands, I Convenient Syntheses of the Trimethylene-linked Triphosphines RP[(CH2)3PPh2]2 and their Precursors Ph2P(CH2)3P(H)R (R = Ph, Me) The secondary-tertiary diphosphines Ph2P(CH2)3P(H)Ph (2) and Ph2P(CH2)3P(H)Me (3) have been prepared from Ph2P(CH2)3Cl (1) and NaP(H)Ph or LiP(H)Me, respectively. Metallation of 2 and 3 with n-butyl lithium and further reaction of the lithio-derivatives with one equivalent of 1 yields PhP[(CH2)3PPh2]2 (4) and MeP[(CH2)3PPh2]2 (5). The tritertiary phosphines 4 and 5 have likewise been obtained from RPLi2 (R = Ph, Me) and two equivalents of 1. The synthesis of 4 from PhPCl2 and two equivalents of the Grignard reagent of 1 is also reported. Each of the phosphines 1-5 was characterized by NMR and mass spectroscopy.

 Title    Bis(?? 5 -cyclopentacüenyl)N,N-Disiibstituted Dithiocarbamato(cUoro)oxomolybdeniim(VI) Complexes  
 Abstract    Bis(?j 5 -cyclopentadienyl)N,N-disubstituted Dithiocarbamato(chloro)oxomolybdenum(VI) complexes of the type (C5H5)2MoO(S2CNR2)C1 and (CsHshMoO^CNRR'JCl where R = Me, Et, «'-Pr and R' = cyclohexyl (cyhx) have been prepared by the reaction of stoichio- metric amounts of bis(^5-cyclopentadienyl)oxomolybdenum(VI) dichloride with sodium dichio-thiocarbamates in refluxing dichloromethane. Infrared spectral studies demonstrate that in these complexes, the dithiocarbamate ligands are bidentate. Hence a coordination number of 7 may be assigned to the molybdenum(VI) atom in each case. In addition to infrared studies, electronic spectra, NMR studies, magnetic susceptibility, elemental analyses and conductance measurements have been carried out for these complexes.

X-ray structure analysis of (^-methyl acrylate)2W(CO)4 reveals the trans-staggered arrangement of the olefinic ligands. Rotational barriers are determined by variable temperature NMR spectroscopy.

 Title    Salts of Ferricinium Cation and its Homologues: NMR Investigation, II EPR and NMR Spectra of sym-Polymethyl Substituted Ferricinium Cations  
 Abstract    The EPR, iH and 13 C NMR spectra of methylferricinium hexafluorophosphates, [(MenCp)2Fe]PFö, n — 0-5, have been recorded. HFS constants have been estimated for all the ligand atoms. The general pattern of the spin density distribution is shown to depend on the superposition of the various mechanisms of spin derealization. For the majority of the cations the determining factors has been found to be represented by spin polarization over the jr-skeleton.

 Abstract    The lithiumphosphido complex cis-Mo(CO)4(Me2PLi)2 reacts with dichlorophosphines RPCI2 (R = Ph, Bu') to give coordination compounds of tetraphosphines Me2P-PR-PR-PMe2, whereas the complex of the triphosphine eis -Mo (CO)4 (Ph2P-PMe-PPh2) is obtained starting with the lithiumphosphido complex cis-Mo(CO)4(Ph2PLi)2. Phenyldilithiumphosphine and the chlorophosphine complexes cis-Mo(CO)4(R2PCl)2 (R = Me, Ph) give in low yield cis-Mo(CO)4(R2P-PPh-PPh-PR2) and cis-Mo(CO)4(R2P-PPh-PR2). The mechanisms of these reactions are discussed. The {3ippjj-and { 1 H} 31 P-NMR spectra are analysed and correlated with the structures of these complexes.

 Title    Quantitative Evaluation of the Reactivity of Alkylating Agents  
 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 13 C chemical shifts of the a-methylene. The method was successfully applied for the ranking of "soft" alkylating agents of low reactivity. It was recently found that "soft" alkylating RI
