Hindered, electron-deficient alkenes 5-11 have been prepared, including analogues of maleic anhydride, Nphenylmaleimide and benzoquinone. Cyclic voltammetry showed that most of these compounds can undergo reduction to form relatively persistent radical-anions, which can mediate the reductive cleavag
