Abstract:Incorporation of tellurium into polycyclic compounds may endow them with unique chemical and optoelectronic properties which are not observed in their lighter chalcogen analogues. Herein, a telluropyran‐containing polycyclic compound (T1) synthesized through a ring‐expansion reaction from the corresponding tellurophene analogue can be reversibly oxidized into halogen adducts T1•X2 (X=Cl, Br, I) with the formation of two Te−X bonds. Their chemical structures have been verified by two‐dimensional 1H‐1H correlati… 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.
