The concept of odd-electron σ-bond was first proposed by Linus Pauling. Species containing such a bond have been recognized as important intermediates encountered in many fields. A number of radicals with a one-electron or three-electron σ-bond have been isolated, however, no example of a diradical based odd-electron σ-bonds has been reported. So far all stable diradicals are based on two s/p-localized or π-delocalized unpaired electrons (radicals). Here, we report a dication diradical that is based on two Se:Se three-electron σ-bonds. In contrast, the dication of sulfur analog does not display diradical character but exhibits a closed-shell singlet. In the part of experimental materials, we found many familiar compounds, such as 1,2-Diphenyldisulfane(cas: 882-33-7Application In Synthesis of 1,2-Diphenyldisulfane)
1,2-Diphenyldisulfane(cas: 882-33-7) belongs to ethers. Ethers lack the hydroxyl groups of alcohols. Without the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other. Application In Synthesis of 1,2-Diphenyldisulfane
