Die Bisanhydride (I) werden nach Literaturverfahren zu den literaturbekannten Bisimiden (IIa) und (IIb) sowie dem erstmalig erhaltenen Bisimid (IIc) umgesetzt.
Durch Reaktion von 1,6‐ Pyrenchinon (I) mit HCl in Eisessig bei Gegenwart von F eC13 oder durch Kochen von (I) mit konz HCl bei Gegenwart von FeCl3 werden die Chlorderivate (II) und (III) erhalten und chromatographisch getrennt.
1,6‐Pyrenequinone (I) and 1,8‐pyrenequinone (V), in the presence of Lewis acids or conc. H2SO4, react with the aliphatic alcohols (II) to yield the monoalkoxy derivatives (III) or (VI) and the dialkoxy derivatives (IV) or (VII).
The title compounds(I) are converted to the corresponding uncleaved sodium or potassium derivatives by gentle heating in the presence of NaOH or KOH, as is shown by the conversions of (Ia) and (Ic) to the corresponding compounds (IIa) and (IIb).
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.
