Electron-transfer-induced valence isomerization of 2,2′-distyrylbiphenyl

Upon chemical or electrochemical reduction, 2,2′-distyrylbiphenyl (1) rearranges into the "bis-benzylic" dianion, 32-, which can be either protonated to a 9,10-dibenzyl-9,10-dihydrophenanthrene or oxidatively coupled to a cyclobutane species. The mechanism of the electron-transfer-induced skeletal rearrangement is studied by product analysis and by cyclic voltammetry, and the results are compared with the outcome of the photolytic [2 + 2] cycloaddition.
