The title anion (3) having a C3v symmetric structure was generated from newly synthesized tristyrylmethane (4) and was characterized by means of 1H and 13C NMR spectroscopy. The pKa value of 4 was determined as 20.1 in DMSO–EtOH (9:1), indicating considerable conjugative stabilization of the anion 3. The cyclic voltammetry of 3 in acetonitrile exhibited only irreversible one-electron oxidation peak corresponding to the formation of a chemically unstable radical species. Whereas quenching the anion 3 with H2O or Me3SiCl quantitatively afforded the cross-conjugated triene 6 (R=H or Me3Si), the reaction of 3 with the tropylium ion yielded 1,1′-bicycloheptatrienyl (29%), as well as the triene 6 (R=C7H7) (66%), demonstrating that 3 can also acat as a one electron reductant.
