 Title    Bis(trimethylsiloxy)tin(II): A Heterosiloxane as Soft Ligand  
 Abstract    Contrary to earlier reports the reaction of sodium trimethylsilanolate with stannous chlo-ride does not yield bis(trimethylsiloxy)tin(II) (1) but a polynuclear compound of the type Sn20(0SiMe3)2 (2). 1 is obtained from the reac-tion of stannocene with trimethylsilanole. The compound is a dimer that gives rapid exchange reactions of terminal and bridging trimethylsil-oxy groups in inert organic solvents.

 Title    Kristallstruktur yon Pyrrolidinium-bis(diisopropylphosphinoyl)phosphid, einem System mit zweifach koordiniertem Phosphor Crystal Structure of Pyrrolidinium-bis(diisopropylphosphinoyl)phosphide, a System with Bicoordinated Phosphorus  
 Abstract    Pyrrolidinium-bis(diisopropylphosphinoyl)phosphide crystallizes triclinically in the space group Pi with a = 1019.6(8), b = 1271.5(4), c = 999.5(7) pm, a = 100.90(5)°, ß = 91.24(5)°, y = 99.10(5)° and Z = 2 formula units. The mean P-P bond length is 212.2 pm and hence shorter than in derivates in which the electron pairs of the bicoordi-nated phosphorus atom are bonded to one or two M(CO)5-groups. Additional p.-z-d* bonding explains the shortening of the P-P bond.

 Abstract    The reactions of dicarbonyl dinitrosyl iron with tri-fertf-butylphosphine, di(feri-butyl)-trimethylsilyl-, -germyl-, -stannyl-phosphine, ferZ-butyl-bis(trimethylsilyl)-, -(germyl)-, -(stannyl)phosphine, as well as with tris(trimethylsilyl)-, -(germyl)-, and -(stannyl)phos-phine result in the elimination of one CO ligand and the formation of the corresponding carbonyl dinitrosyl organometalphosphine iron complexes. The IR, X H, 31 P, 13 C, and 119 Sn NMR spectra of the new complexes are reported and discussed.

 Title    N-Methylcarbamoylphosphate, I. Synthese N-Methylcarbamoyl Phosphates, I. Synthesis  
 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 31 P NMR measurements. Various types of compounds, including a coordination compound of cobalt could.be isolated in crystalline form: [Et3NH]HX, KHX, NH4HX, Na2X • H20, MgX • 4 H20, CaX • H20, SrX • 2 HaO, BaX • H20, ZnX • 5 H20, CdX • 2 H20, [(NH3)5COX]C104, [EtsNHjY, AgY • MeCN, X = MeNHC(0)0P03, Y = [MeNHC(0) 0]2P02.

 Title    A New Synthesis of Organodifluorophosphites and their Reactions with Platinum(II) Complexes  
 Abstract    Alkyldifluorophosphites, ROPF2 (R = ^-substituted benzyl group, neopentyl, 1-ada-mantyl) have been obtained by a new method, involving reaction of the appropriate alkyl trimethylsilylether, ROSiMe3 with chlorodifluorophosphine, PF2C1. Reactions of these difluorophosphites with platinum(II) complexes of the type [LaPtCla] (L = PEt3, PPI13) led to products such as irans-[L2PtCl(POF2)] and {[p-XC6H4CH2PPh3]+}2[Pt(POF2)4] 2 -, (X = H, Me, Cl, N02). The ease of carbon-oxygen cleavage in ROPF2 is characteristically related to the nature of the leaving group, R.

 Title    Überführung von Triazaphospholen in Diazaphosphole durch Acetylenaddition/Nitrileliminierung [1] Conversion of Triazaphospholes into Diazaphospholes by Acetylene Addition/Nitrile Elimination [1]  
 Abstract    Acetylene di-and (less easily) monocarboxylic esters replace nitriles from the 4,5-position of 1,2,4,3-triazaphosphole rings to give carboxyl derivatives of 1,2,3-diaza-phospholes, presumably by a cycloaddition/cycloreversion mechanism. In cases with a mobile N-substituent alternatively the loss of N2 seemed feasible, but was normally not observed.

 Abstract    5-Bromo-uracil (2) with chloro-diphenylphosphine and triethylamine gives 5-bromo-N(1),N(3)-bis(diphenylphosphino)-uracil (3). In moist acetone, 3 is hydrolyzed to 5-bromo-N(l)-diphenylphosphino-uracil (4). 3 reacts with n-butyllithium under rearrangement and, with HCl, under elimination of a PPh2-group, forms C(5)-diphenylphosphino-uracil (7 a). Recrystallization of 7 a from ethanol yields the ethanol-1:1-adduct 7 b. Heating of 7 a in dimethylsulfoxide with D20 yields the N(l),N(3)-dideutero-C(5)-diphenylphosphino-uracil (7 c). All compounds were characterized by infrared, Raman, iH, 31 P NMR and mass spectra. 7 a shows a very small antitumor activity.

 Title    Über das [C7H7Fe2(CO)5]--Anion (C7H7 = Cycloheptatrienyl) About the [C7H7Fe2(CO)5]--Anion (C7H7 = Cycloheptatrienyl)  
 Abstract    The extremely unstable anionic complex [C7H7Fe2(CO)6]~ (C7H7 = cycloheptatrienyl) which decomposes in polar solvents under CO elimination to give [C7H7Fe2(CO)s]~ can be prepared by deprotonation of C7H8Fe2(CO)6 (C7H8 = cycloheptatriene) with NaN(SiMe3)2 in CßHe-The NMR spectra of [C7H7Fe2(CO)5]~ show the highly fluctional character of this anion in solution. The X-ray structural parameters of Ph4As[C7H7Fe2(CO)5] (space group P2i/n) can be interpreted in terms of a rotation of the tub shaped C7H7 ring against the CO bridged Fe2(CO)5 fragment in the solid state. Consequently, each iron atom is alternatingly rj 3 -or ^-coordinated to the allyl anion and the diene part, respectively, of the anionic 8n system of the cycloheptatrienyl ring.

(cod)Rh(Cl)P(CH3)3 (cod = 1.5-cycloocta-diene), obtained by cleavage of [(cod)RhCl]2 with P(CH3)3, reacts with 6.6-dimethyl-fulvene and CH3Li or i-C3Ü7MgBr with substitution of cod by dimeric fulvene ligands the nature of which depends on the alkyl reagent. The new complexes were characterized by NMR spectra and in one case by X-ray diffraction analysis.

 Title    Chemistry of Poly functional Molecules, 75 [1] The Reaction of 5-Bromo-uracil with Sodium Diphenylphosphide  
 Abstract    5-Bromo-uracil (1) reacts with sodium diphenylphosphide or a mixture of sodium diphenylphosphide and sodium amide in liquid ammonia to give sodium 5-bromo-uracilate (5 a). From water 5 a crystallizes with one mole H2O yielding 5b. Treatment of 5 a with D2O yields sodium 5-bromo-N-deutero-uracilate-D20 (1/1) (5 c). With chlorodiphenyl-phosphine 5a forms 1-diphenylphosphino-uracil (2). 5a, b, c show N(l)-N(3)-(H/D)-tauto-merism in concentrated D2O solutions already, but in DMSO or Dö-DMSO only in dilute solutions. All the compounds were characterized by infrared, Raman, X H NMR, UV spectra and conductometry.
