    Description / Table of Contents: Attempts to Stabilize Nitrile Sulfides at the Metal. Reactions of 5-R-1,3,4-Oxathiazol-2-ones with (Triphenylphosphane)palladium(0) and -platinum(0) Compounds: N-Thiohydroximato ComplexesOxathiazolones (1) are added oxidatively to (triphenylphosphane)platinum(0) and -palladium(0) compounds to give carbon monoxide and the complexes 2 and 3 with the dianion of N-thiohydroximic acid and its derivatives as chelating ligands. The structure of 2g was determined by x-ray analysis.
    Notes: Oxathiazolone (1) addieren sich oxidativ an (Triphenylphosphan)platin(0)- und -palladium(0)-Verbindungen unter Abspaltung von Kohlenmonoxid und Bildung der Komplexe 2 und 3 mit dem negativ zweiwertigen Anion von N-Thiohydroximsäure bzw. deren Derivate als Chelatliganden. Die Struktur von 2g wurde röntgenographisch bestimmt.

    Description / Table of Contents: Strong Organometallic Lewis Acids, II. Reaction of (η5-C5H5)(OC)3MoBF4 with Water. Structure of a Tris(metallo)oxonium Cation {[(η5-C5H5)(OC)2Mo]3O}+The reaction of (η5-C5H5)(OC)3MoBF4 with water vapour at 20°C yields the aqua complex [(η5-C5H5)(OC)3Mo(OH2)]+BF4- (1). The aqua ligand in solid 1 forms hydrogen bridges to the BF4- anion. With an excess of water 1 gives the hydrate [(η5-C5H5)(OC)3Mo(OH2)]+BF4- · n H2O (n ≍ 3) (2). From a solution of 1 the tris(metallo)oxonium salt {[(η5-C5H5)(OC)2Mo]3O}+BF4- (3) has been isolated. The X-ray structure of 3 was determined.
    Notes: (η5-C5H5)(OC)3MoBF4 setzt sich mit Wasserdampf bei 20°C zum Aquakomplex [(η5-C5H5)(OC)3-Mo(OH2)]+BF4- (1) um. Der Aqualigand in 1 bildet in festem Zustand Wasserstoffbrücken zum BF4--Anion aus. Mit überschüssigem Wasser entsteht aus 1 ein Hydrat [(η5-C5H5)(OC)3Mo-(OH2)]+ BF4-·n H2O (n ≍ 3) (2). Aus einer Lösung von 1 entsteht das Tris(metallo)oxonium-Salz {[(η5-C5H5)(OC)2Mo]3O}+BF4- (3), dessen Struktur röntgenographisch bestimmt wurde.

    Description / Table of Contents: At first a short review is given with respect to an automatic streaming potential measurement and to the ultrasonic vibration potential method. The ultrasonic vibration method has advantages but the main barrier to a direct application in a mill is the influence of a great electrlyte cocentration. A solution of this problem is of interest. Useful applications of this method in the laboratory are described: basic research with ionic polymers, measurements to the influence of disturbing substances, filler preflocculation.
    Notes: Zunächst wird der Stand der Entwicklung für eine automatische Strömungspotential-Appartur und eine praxisgerechte Ultraschall-Elektrophorese-Apparatur geschildert. Bei der zweiten Methode erschwert hoher Elektrolytgehalt die Anwendung an einer Papiermaschine. Mögliche Auswege werden noch erprobt. Im Labor hat diese Methode jedoch schon vielfältige Anwendungen ermöglicht, wie z. B. bei Untersuchungen über die Wirkungsweise von Retentionsmitteln, den Einfluß von Störsubstanzen und die Füllstoff-Aktivierung.
