    Description / Table of Contents: On the Nucleophilic Degradation of Tris(pentasulfido)platinum(IV), [Pt(S5)3]2-, and Bis(pentasulfido)platinum(II), [Pt(S5)2]2-The behaviour of [Pt(S5)3]2-, (I), towards sulfite, arsenite, sulfide, hydroxide, and triphenylphosphine has been studied qualitatively and quantitatively. With stoichiometric amounts of nucleophile one ring is degraded; the reaction product [Pt(S5)2]2-, (II), can be isolated. With excess of nucleophile all sulfur atoms are taken off from the platinum; with triphenylphosphine, however, (PPh3)2PtS4, (III), is formed. A mechanistic interpretation of the course of the reaction is given and supported by kinetic studies.
    Notes: Das Verhalten von [Pt(S5)3]2-, (I), gegenüber Sulfit, Arsenit, Sulfid, Hydroxid und Triphenylphosphin wird qualitativ und quantitativ untersucht. Mit stöchiometrischen Mengen an Nukleophil wird ein Ring abgebaut; als Reaktionsprodukt kann [Pt(S5)2]2-, (II), isoliert werden. Mit Überschuß an Nukleophil werden alle Schwefelatome vom Platin abgelöst; mit Triphenylphosphin entsteht dagegen (PPh3)2PtS4, (III). Der Reaktionsablauf wird mechanistisch gedeutet und durch kinetische Untersuchungen erhärtet.

    Description / Table of Contents: Acyl- and Alkylidenephosphines. XXXII. Di-cyclohexoyl- and Diadamant-1-oylphosphine - Keto-Enol Tautomerism and StructureLithium dihydrogenphosphide · DME (1) [12] and cyclo-hexoyl or adamant-1-oyl chloride react in a molar ratio of 3:2 to give lithium di-cyclo-hexoylphosphide · DME and the corresponding diadamant-1-oylphosphide.2THF (1) resp. Treatment of these two compounds with 85% tetrafluoroboric acid. diethylether adduct yields di-cyclo-hexoyl- (1b) and diadamant-1-oylphosphine (1c). In nmr spectroscopic studies 1b over a range of 203 to 343 K, a strong temperature dependence of the keto-enol equilibrium is found; thermodynamic data characteristic for the formation of the enol tautomer (ΔH0 = -4.3 kJ. mol-1; ΔS0 = -9.2 J. mol-1. K (-1) are compared of 1,3-diketones.The enol tautomer of diadamant-1-oylphosphine (E-1c) as obtained from a benzene solution in thin colourless plates, crystallizes in the monoclinic space group P21/c {a = 722.2(2); b = 1085.5(4); c = 2434.8(5) pm; ß = 96.43(2)° at -100 ± 3°C; Z = 4}. An X- ray structure analysis (Rw = 0.033) shows bond lengths and angles to be almost identical within the enolic system (P—C 179/180; C—O 130/129; C—C(adamant-1-yl) 152/153 pm; C—P—C 99°; P—C—O 124°/124°; P—C—C 120°/120°; C—C—O 116°/116°. The geometry of the very strong, but probably asymmetric O‥H‥O bridge is discussed (O—H 120/130, O‥O 245 pm).

Die Lage des Keto-Enol-Gleichgewichts zwischen 203 und 343 K sowie thermodynamische Daten zur Bildung des Enol-Isomers ΔH0= -4,3kJ.Mol-1; ΔS0;=-9,2 J · mol-1 · K-1 () wurden NMR-spektroskopisch an einer 2 M Lösung des bei +20°C flüssigen Di-cyclo-Hexoyl-Derivates 1b in d8-Toluol ermittelt und mit Werten von 1,3-Diketonen verglichen.Das farblose, sich aus Benzol in dünnen Plättchen abscheidende Enol-Tautomer des Diadamant-1-oylphosphans (E-1 c) kristallisiert monoklin in der Raumgruppe P21/c {a = 722,2(2) b = 1085,5(4); c = 2434,8(5) pm; ß = 96,43(2)° bei - 100 ± 3°C; Z = 4}. Nach den Ergebnissen der Röntgenstrukturanalyse (Rw=0,033) weist das Molekül in beiden des Hälften des Enolrings nahezu identische Bindungslängen und -winkel auf P—C 179/180; C—O 130/129; C—C(Adamant-1-yl) 152/153 pm; C—P—C 99°; P—C—O 124°/124°; P—C—C 120°/120°; C—C—O 116°/116°. Die Geometrie der sehr starken, aber vermutlich asymmetrischen O‥H‥O-Brücke wird diskutiert (O—H 120/130; O‥O 245 pm).

    Description / Table of Contents: The product prepared following the method of GOEHRING and FELDMANN from H2S2O3 and S2Cl2 is not a „spectrum“ of different salts as stated by WEITZ and BECKER, but really K2S6O6, which is also prepared from H2S2O3 and HNO2. Tetrasulfane-disulfonate does not only exist in the neutral form K2S6O6, but also in a „acid“ form with a part of the potassium - nonstoichiometrically - replaced by H+. The two forms have different shape and X-ray spectra.
    Notes: Bei dem nach GOEHRING und FELDMANN aus H2S2O3 und S2Cl2 dargestellten Produkt handelt es sich nicht, wie von WEITZ und BECKER angegeben, um ein „Spektrum“ verschiedener Salze, sondern um einheitliches K2S6O6, wie es auch aus H2S2O3 und HNO2 erhalten wird. Tetrasulfan-disulfonat existiert neben der neutralen Form K2S6O6 noch in einer „saueren“ Form, bei der ein Teil des Kaliums - nichtstöchiometrisch - durch H+ ersetzt ist. Die beiden Formen unterscheiden sich in Aussehen und Röntgenspektrum voneinander.

    Description / Table of Contents: The separation of sulfane-disulfonates, sulfite and thiosulfate by anion-exchangers has been studied. Whereas K2S6O6 is decomposed on the column, the salts K2S3O6, K2S4O6 and K2S5O6 may be separated quantitatively.
    Notes: Die Trennung von Sulfan-disulfonaten, Sulfit und Thiosulfat mit Anionenaustauschern wird untersucht. Während K2S6O6 auf der Säule zu rasch zerfällt, lassen sich die Salze K2S3O6, K2S4O6 und K2S5O6 quantitativ voneinander trennen.

    Description / Table of Contents: The solubilities of the sulphur modifications S6 and S12 in carbon disulphide and benzene have been determined. They form „regular“ solutions. The solubility differences are big enough for a separation of S6, S8 and S12 via fractional crystallisation.
    Notes: Die Löslichkeiten der Schwefelmodifikationen S6 und S12 in Schwefelkohlenstoff und Benzol wurden bestimmt. Sie bilden darin „reguläre“ Lösungen. Die Unterschiede in den Löslichkeiten ermöglichen eine Auftrennung von S6, S8 und S12 durch fraktionierte Kristallisation.
