    Notes: Zusammenfassung Die Ionenaustauscher als hochdisperse Systeme haben das Forschungsgebiet des Kolloidchemikers beträchtlich bereichert. Mittels solcher Adsorbentien ist u. a. die Trennung von Stoffen möglich geworden, deren Dimensionen an der Grenze zwischen der kolloiden und molekularen Welt liegen. Die vielseitigen Reaktionsmöglichkeiten mit Kolloiden, wie sie durch die Einzelbeispiele illustriert worden sind, bedeuten eine Erweiterung des RÜstzeugs der wissenschaftlichen und technischen Kolloidchemie.

    Synthese von 2-Heterocyclidenamino-1,3-diazatrimethincyaninen (1979)
    New York, NY : Wiley-Blackwell
    Journal für Praktische Chemie/Chemiker-Zeitung 321 (1979), S. 827-834

    Notes: Synthesis of 2-Heterocyclidenamino-1, 3-diaza-trimethincyaninesThe synthesis of 2-[3-methyl-benzthiazol-(1, 3)-inylidene-(2)-amino]- and of substituted 2-[1, 3-dithiolyliden-(2)-amino]-1, 3-diaza-trimethincyanines is described. The heterocyclic imines 1 react with phosgene or thiophosgene to the corresponding ureas 2 and thiureas 3, respectively. Alkylation of 3 to the 2-alkylmercapto-1, 3-diaza-trimethincyanines 4 and subsequent condensation with imine 1 yields the dyes 5. The chemical and spectroscopical data of cyanines 5 are described.
