    S-(N-(Thiocarbamoyl)benzimido)-dithiocarbamidsäureester (1996)
    Springer
    Monatshefte für Chemie 127 (1996), S. 291-296 
    Details
    ISSN: 1434-4475
    Keywords: S-(N-(Thiocarbamoyl)benzimido)dithiocarbamic esters ; Synthesis ; 13C NMR spectroscopy ; Side reactions
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Description / Table of Contents: Summary The synthesis of the title compounds3 (R 1=R 2=C2H5;n-C4H9) by reactions of N-(N′,N′-diethylthiocarbamoyl)benzimidechloride (2) with sodiumdialkyldithiocarbamates (1) in acetone is described. The low yields (〈25%) are caused by the occurrence of side reactions. The structures of the compounds were confirmed by IR,1H and13C NMR, and mass spectroscopy. Side reactions were detected by13C NMR spectroscopy; the results are discussed.
    Notes: Zusammenfassung Die Synthese der Titelverbindungen3 (R 1=R 2=C2H5;n-C4H9) durch Reaktionen von N-(N′,N′-Diethylthiocarbamoyl)-benzimidoylchlorid (2) mit Natriumdialkyldithiocarbamaten (1) in Aceton wird beschrieben. Die niedrigen Ausbeuten (bis 25% d.Th.) sind durch Nebenreaktionen bedingt. Die Strukturen der Verbindungen werden durch IR-,1H-NMR-,13C-NMR-und Massenspektren bestätigt. Nebenreaktionen werden13C-NMR-spektroskopisch verfolgt und die Ergebnisse diskutiert.

    Soil organic matter composition and pesticide bonding in sandy soils in relation to groundwater protection in the Northwest German Lower Plain (1996)

    Notes: Abstract In sandy gleyic soils with a low groundwater table under arboriculture in Northwest Germany, a wide variation of groundwater pollution by pesticides has been observed. We therefore examined data on microbial activity and soil organic matter composition by wet chemistry, cross-polarization magic-angle spinning and 13C nuclear magnetic resonance, and pyrolysis–field ionization mass spectromy. However, neither microbial activity nor the soil organic matter composition of cultivated topsoils explained the differences in xenobiotic leaching into the groundwater. Data from Anthrosols suggested that these soils have a higher capacity for pesticide bonding because of high amounts of aromatic and carboxylic C moieties in the soil organic matter. However, despite the same pesticide inputs and time of application, the leached output from these soils was higher than that from the Podzols. Initial data from subsoil investigations suggest that the presence of a spodic horizon most likely reduces groundwater pollution by pesticides. Studies to assess fixation capacity and desorption kinetics in Bh horison seem warranted.
