Before revision: Electrochemical measurements show that TTF can be oxidized twice reversibly: Each dithiolylidene ring in TTF has 7π electrons: 2 for each sulfur atom, 1 for each sp2 carbon atom.
After revision: (E = 0.34 V) (E = 0.78 V, vs. Ag/AgCl in MeCN solution)Electrochemical measurements show that TTF can be oxidized twice reversibly: Each dithiolylidene ring in TTF has 7π electrons: 2 for each sulfur atom, 1 for each sp2 carbon atom.
