    Notes: Während die Brom-Austreibung in Gegenwart von Sulfaten in allen Konzentrationen des betreffenden Salzes, je nach dem an- gewandten Sulfat, entweder beschleunigt oder verzögert wird, wirken alle Chloride niederer Konzentration ausschließlich verzögernd. Überall hat man ein Maximum der Verzögerung im Gebiet von etwa n/1-Endkonzentration. Es ergibt sich folgende Reihe ab- nehmender Verzögerung: \documentclass{article}\pagestyle{empty}\begin{document}$$ Me^I Cl 〉 Me^{II} Cl_2 \ge Me^{III} Cl_3. $$\end{document}Eine spezifische Kationenwirkung ist nicht feststellbar. HCl ver- hält sich genau wie ein neutrales Chlorid. Das H-Ion liegt in seiner Wirkung zwischen den ein- und mehrwertigen Kationen.

Penicillium adametzi hydroxylates the substrate at the 7-methyl substituent, whereas 1 -ethyl-8-methoxy-5-methyl-4-oxo- 1,4-dihydroquinoline-3-carboxylic acid (4) is hydrolyzed to the free phenol by the same fungi. l-Ethyl-4-oxo-1,4,6,7,8,9-hexahydrobenzo[g]quinolinc-3-carboxylic acid (6) is hydroxylated in 7 - and 8-position by Penicillium adametzi, in 6- and 7- (or 8-) position by Streptomyces achromogenes and in 6-position by Sporotrichum sulfurescens. 5-Ethyl-8-oxo-2,3,5,8-tetrahydrofuro[2,3-g]quinoline-7-carboxylic acid (10) undergoes only a hydrolytic cleavage of the dihydrofuranering.

    Notes: 1,2,3-Tricarbonyl Compounds, XII. Elucidation of the Constitution of the Reaction Products of Ninhydrin with 2-Aminophenol and 2-AminothiophenolNinhydrin (1) reacts with 2-aminophenol (2) and 2-aminothiophenol (6) to give products the constitutions of which were elucidated by means of the 1H- and 13C NMR spectra to be 10a-hydroxy-indeno[2,1-b]benz[1,4]oxazine-11(10aH)-one (3) and 10a-hydroxy-indeno[2,1-b]benz-[1,4]thiazine-11(10aH)-one (7), respectively. Structures mentioned in the literature are on the one hand corrected and on the other hand doubtless established.

    Description / Table of Contents: Microbiological Transformations of Nonsteroidal Structures, III. Hydroxylation of 5-Alkyl-2-(benzenesulfonylamino)pyrimidines and Structurally Related Antidiabetics5-Alkyl-2-(arylsulfonylamino)pyrimidines (1-5 and 11-16) have been hydroxylated microbiologically Propyl, butyl, and isobutyl groups were hydroxylated at C-2, ethyl groups at C-1, isopropyl groups at C-1 and C-2, and neopentyl groups at C-3, respectively, by Streptomyces griseolus. The sulfonylurea part of the antidiabetics glibenclamid (25) and glisoxepid (29) was degradated to sulfonamide; in addition, hydroxyl groups were introduced into the 2- and 4-positions of the cyclohexane ring of 25.
    Notes: 5-Alkyl-2-(arylsulfonylamino)pyrimidine (1-5 und 11-16) wurden mikrobiologisch hydroxyliert. Mit Streptomyces griseolus wurden Propyl-, Butyl- und lsobutylgruppen an C-2, äthylgruppen an C-1, Isopropylgruppen an C-1 und C-2, sowie Neopentylgruppen an C-3 hydroxyliert. Die Antidiabetika Glibenclamid (25) und Glisoxepid (29) mit Sulfonylharnstoff-Struktur wurden zu Sulfonamiden abgebaut, ferner wurden in 2- und 4-Stellung des Cyclohexanrings von 25 Hydroxylgruppen eingeführt.

    Description / Table of Contents: The compounds of the type MeICuS4 (with MeI = NH4+, K+, Rb+, and Cs+) are no true tetrathiocuprates(I) but metal(I)-copper(I)-tetrasulfides, as shown by X-ray data and by infrared and visible light spectra. The existence of corresponding metal(II)-copper(I)-tetrasulfides seems to be doubtful.It was shown by hydrolysis and thermal decomposition of NH4CuS4 that CuSX compounds with x ≥ 1 are in fact mixtures of CuS and sulfur.
    Notes: Mit Hilfe röntgenographischer Methoden und unter Verwendung von Spektren im infraroten und sichtbaren Bereich wurde nachgewiesen, daß die Verbindungen vom Typ MeICuS4 (mit MeI = NH4+, K+, Rb+ und Cs+) keine echten Tetrathiocuprate(I) sind, sondern Metall(I)-Kupfer(I)-tetrasulfide darstellen. - Die Existenz der entsprechenden Metall(II)-Kupfer(I)-tetrasulfide wird in Frage gestellt.Die hydrolytischen und thermischen Zersetzungen von NH4CuS4 ergaben, daß die in der Literatur beschriebenen Verbindungen vom Typ CuS≥1 Mischungen aus CuS und Schwefel sind.
