ChemInform Abstract The tetralindicarbonitrile (I), prepared from 1,1,4,4,6,7-hexamethyltetralin by common methods, is treated with sodium isoamylate to give the phthalocyanine (II). Cyclization in the presence of vanadyl, cobalt, copper, or zinc salts results in the formation of the corresponding metal phthalocyanines.
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.
