Abstract:
Herein, we report the record-breaking seven-electron reduction of di-iso-propylphenyl-bis-iminoacenaphthene (dpp-bian) involving protons under chemical and electrochemical reduction conditions. Using the dpp-bian-H2 compound as a starting reagent, its mono- and trisodium salts were obtained. A voltammetric study showed that the trinuclear sodium salt can accept an additional seventh electron upon electrochemical reduction.

Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is...
