Summary. The behaviour of di-(1-anthraquinony1)-aminc, when cyclised in pyridine-aluminium chloride or pure aluminium chloride fusions, has bcen comparcd. The formation of blue educt complexes with aluminium chloride in the latter case has been revealed as a factor which inhibits cyclisation. The results are discussed and generaliscd, classifying carbazolation of anthrimides as an intramolecular SchoZZ-type reaction.In der letzten Mitteilung L l ] haben wir iiber die Carbazolierung von Di-(1-anthrachinony1)-amin (1)
An anomalous type of FRIEDEL‐CRAFTS reaction was observed with hexaethyland hexamethylbenzene. With a number of acid chlorides and γ‐dicarboxylic anhydrides the reaction proceeded by elimination of an alkyl group with production of the corresponding pentaalkylphenyl ketones and γ‐pentaalkylbenzoyl acids respectively.
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.
