    Description / Table of Contents: π-Complexes of 1-Methyl-3,5-diphenylthiabenzene 1-Oxide with Tricarbonylchromium, -molybdenum, and -tungsten1-Methyl-3,5-diphenylthiabenzene 1-oxide (1) reacts with the tris(acetonitrile)tricarbonyl complexes of chromium, molybdenum, and tungsten to yield red air-stable complexes of the composition tricarbonyl(1-methyl-3,5-diphenylthiabenzene 1-oxide)metal(0) (2). From the reaction of (CH3CN)3Cr(CO)3 with the heterocycle two isomers 2a and 2d are obtained. Their molecular structures are elucidated by X-ray analysis. From this it is evident that the complexed ligand is non-planar. There are no bonding interactions between the metal and the sulfur atom.
    Notes: 1-Methyl-3,5-diphenylthiabenzol-1-oxid (1) reagiert mit den Tris(acetonitril)tricarbonyl-Komplexen von Chrom, Molybdän und Wolfram zu roten luftstabilen Komplexen der Zusammensetzung Tricarbonyl(1-methyl-3,5-diphenylthiabenzol-1-oxid)metall(0) (2). Aus der Reaktion von (CH3CN)3Cr(CO)3 mit dem Heterocyclus werden zwei Isomere 2a und 2d erhalten, deren Molekülstruktur durch Röntgenstrukturanalyse aufgeklärt wurde. Dabei zeigte sich, daß der komplexierte Ligand nicht planar ist und das Metall keine Bindung zum Schwefelatom ausbildet.

The Deoxygenation of anti-Tricarbonyl(1-methyl-3,5-diorganyl-λ6thiabenzene oxide)chromium,-molybdenum, and -tungsten as a Novel Synthetic Route to λ4-Thiabenzene ComplexesFrom the reaction of anti-configurated λ6-thiabenzene oxide complexes 5a-e, 6e, and 7e with sodium bis(2-methoxyethoxy)aluminium hydride λ4-thiabenzene complexes 2a-e, 3e, and 4a are obtained. The hitherto unknown ylidic heterocycles in the novel complexes behave as significantly stronger donor ligands as the related λ6-thiabenzene oxides as is inferred from spectroscopic data.
    Notes: Bei der Reaktion der anti-Konfigurierten λ6-Thiabenzoloxid-Komplexe 5a-e, 6e und 7e mit Natrium-bis(2-methoxyethoxy)aluminiumhydrid werden die λ4-Thiabenzol-Komplexe 2a-e, 3e und 4e erhalten. Nach den Spektren sind die bisher unbekannten ylidischen Heterocyclen in den neuartigen Komplexen deutlich stärkere Donorliganden als die entsprechenden λ6-Thiabenzoloxide.

The temperature dependence of the 1H NMR spectra of 3a-f is consistent with a hindered rotation of the ring ligands. The X-ray structure analysis of 3b shows that the molecule in the solid state possesses no local Cs-symmetry.
    Notes: Die 1-Alkyl-3,5-diphenyl-λ4-thiabenzol-Chromkomplexe 2a-f werden durch NOPF6 in CH2Cl2 bei -70°C unter Bildung der kationischen Dicarbonylnitrosyl-Spezies 3a-f oxidiert. Die temperaturabhängigen 1H-NMR-Spektren dieser Komplexe deuten auf gehinderte Rotation der Ringe um das (CO)2(NO)Cr+-Fragment hin. Die Röntgenstrukturanalyse von 3b zeigt, daß das Molekül im Kristall keine lokale Cs-Symmetrie mehr besitzt.

    Description / Table of Contents: Transition-Metal-Substituted Acylphosphanes and Phosphaalkenes, IX. On the Synthesis of Phosphaalkenyl-, Mono- and Diacylphosphido Complexes from the Reaction of [Bis(trimethylsilyl)phosphido]dicarbonyl(pentamethylcyclopentadienyl)iron and Carbonyl ChloridesReaction of the title compound (η5-C5Me5)(CO)2FeP(SiMe3)2 (4) with 2,4,6-trimethylbenzoyl chloride (2a) yields the phosphaalkenyl complex (η5-C5Me5)(CO)2FeP=C(OSiMe3)(Mes) (5a). Treatment of 4 with benzoyl chloride affords the phosphaalkenyl complex 5b and (η5-C5Me5)(CO)2FeP[C(O)Ph]2 (6b), whereas with pivaloyl chloride (2c) 6c is formed as the sole product. The monoacylphosphido complexes 8a-c are generated from the reaction of 4 with acyl chlorides 2a-c in the presence of ethanol. Lithiation by LiCH3 and subsequent acylation with 2,4,6-trimethylbenzoyl chloride converts compound 8a into 6a. Similarily the lithiation product of 8 is transformed into the phosphaalkenyl complexes 5a-c by treatment with Me3SiCl.
    Notes: Die Titelverbindung (η5-C5Me5)(CO)2FeP(SiMe3)2 (4) reagiert mit 2,4,6-Trimethylbenzoylchlorid (2a) zu dem Phosphaalkenylkomplex (η5-C5Me5)(CO)2FeP=C(OSiMe3)(Mes) (5a). Demgegenüber führt die Umsetzung von 4 mit Benzoylchlorid neben dem Phosphaalkenylkomplex 5b zu (η5-C5Me5)(CO)2FeP[C(O)Ph]2 (6b). Aus 4 und Pivaloylchlorid (2c) wird nur noch der Dipivaloylphosphidokomplex 6c gebildet. Führt man die Umsetzungen von 4 mit den Säurechloriden 2a-c in Gegenwart von Ethanol durch, so erhält man die Monoacylphosphidokomplexe (η5-C5Me5)(CO)2FePH[C(O)R] (8a-c). Komplex 8a wird von Methyllithium lithiiert und durch 2,4,6-Trimethylbenzoylchlorid in 6a übergeführt. Desgleichen ergeben die Lithiierungsprodukte von 8 mit Me3SiCl die Phosphaalkenylkomplexe 5a-c.

    Notes: Transition-Metal-Substituted Acylphosphanes and Phosphaalkenes, XXI.  -  Isophosphaalkynes as μ3-Ligands in Transition Metal ComplexesReaction of the μ-isophosphaalkyne complex (η5-C5H5)2 (CO)2(μ-CO)Fe2(μ-CPMes) (Mes = 2,4,6-Me3C6H2) (2a) with [(Z)-Cyclooctene]Cr(CO)5 or Fe2(CO)9 gives rise to the μ3-isophosphaalkyne complexes (η5-C5H5)2(CO)2(μ-CO)Fe2{μ-CP[M(CO)n]Mes} 3a [M(CO)n = Cr(CO)5] and 4a [M(CO)n = Fe(CO)4]. Similarly (η5-C5H5)2(CO)2(μ-CO)Fe2{μ-CP[Cr (CO)5]C6H2(CF3)3-2,4,6} (3d) is obtained. The metal carbonyl fragments are attached to 2 in a η1-fashion by the lone-pair at the phosphorus. In contrast to this the treatment of 2a with (Ph3P)2Pt(η2-C2H4) affords complex 5a in which 2a serves as an η3-3e ligand towards the PtPPh3 moiety. The molecular structures of 3a and 5a are determined by single-crystal X-ray analysis.
