Abstract:Die Metallkomplex-bildenden Farbstoffe 5a-h entstehen durch Kupplung von 2-Methoxy-, 2-Hydroxy-und 2-Carboxy-aryldiazoniumsalzen rnit 6-Hydroxy-chrysen (1) in Pyridin. Chrysenchinon (2) wird rnit o-substituierten Arylhydrazinen zu den Metallchelat-bildenden Azofarbstoffen 6a-f kondensiert. ~ Entmethylierung der 5-Hydroxy-2-methoxy-arylazo-Farbstoffe 5 b und 6b rnit Kobaltnitrat in Pyridin fuhrt zu den Dihydroxy-azo-Verbindungen 5h und 6h. 0'-Hydroxylierung der Monohydroxy-azo-Farbstoffe 3, 7 und 8 ergibt Gemis… Show more
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.
