Zwitterionic inorganic benzene valence isomer with σ-bonding between two π-orbitals. Journal of the American Chemical Society, 140(38), 11921-11925. doi:10.1021/jacs.8b08025 | Journal: | Journal of the American Chemical Society | Abstract: | Despite the large number of plausible isomers of benzene (C6H6), only four valence isomers [(CH)6] have been experimentally detected, all of which are nonionic and possess skeletal frameworks built from localized C-C bonds. Herein, we present the isolation of a diazatetraborabenzene analogue of a hypothetical zwitterionic valence isomer of benzene. Therein, two electrons are delocalized over the four boron atoms in the six-membered B4N2 ring, which is a result of the σ-bonding interaction between two odd-electron B-B π-orbitals. Simple treatment with a crown ether leads to the formation of a paramagnetic potassium-doped radical ion pair that exhibits a thermally populated triplet character. | URI: | https://hdl.handle.net/10356/139272 | ISSN: | 0002-7863 | DOI: | 10.1021/jacs.8b08025 | Schools: | School of Physical and Mathematical Sciences | Rights: | © 2018 American Chemical Society.
