5,8,17,20-Tetrakis(3,5-di-t-butylphenyl)-6,7,18,19-tetradehydrotetrathia[24]annulene (4.0.4.0) shows clear paratropicity (antiaromaticity) and highly amphoteric redox properties, whereas the dianion obtained by its alkali metal reduction strong diatropicity (aromaticity) as a novel 26π-electron system.
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.
