Abstract:Two isomeric series of compounds with “inverted” chains’ substitution patterns, 7,10‐dialkoxy‐1,2,3,4‐tetrafluoro‐6,11‐dimethoxytriphenylene and 6,11‐dialkoxy‐1,2,3,4‐tetrafluoro‐7,10‐dimethoxytriphenylene, labelled respectively p‐TPFn and m‐TPFn, and two non‐fluorinated homologous isomers, 3,6‐dibutoxy‐2,7‐dimethoxytriphenylene and 2,7‐dibutoxy‐3,6‐dimethoxytriphenylene, p‐TP4 and m‐TP4, respectively, were synthesized in three steps and obtained in good yields by the efficient transition‐metal‐free, fluoroare… 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.
