Summary.

 The synthesis of some novel guanylhydrazones of (hetero)aryl methyl ketones is described. Successive reaction with hot acetic anhydride leads to the corresponding N,N′-diacetyl derivatives. Structural assignments of all novel compounds and those of some already known congeners were achieved by means of NMR spectroscopic investigations (1H, 13C) and X-ray structure analysis.

Zusammenfassung.

 Die Synthese einiger neuer Guanylhydrazone von Aryl-bzw. Heteroarylmethylketonen wird beschrieben. Die Reaktion dieser Verbindungen mit Acetanhydrid führt zu entsprechenden N,N′-Diacetylderivaten. Die Strukturen aller neuen Verbindungen sowie die einiger bereits beschriebener Analoga wurden mit Hilfe von NMR-Untersuchungen (1H, 13C) sowie durch Röntgenkristallstrukturanalysen bestimmt.
