Durch Kondensation der Chinoliniumperchlorate (I) mit den Triazenen (II) in siedendem Äthanol, Pyridin oder Dioxan werden die Hydrazone (III) (Ausbeute 27‐56%), analog die Hydrazone (IV) (86‐90%) und (V) (94‐100%) dargestellt.
Beim Erhitzen des Chinaldiniumsalzes (I) mit Jod in trockenem Pyridin wird die Verbindung (III) erhalten, die mit den Nitrosobenzolderivaten (IV) zu den Nitronen (V) reagiert.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
