Graphite reaction
WebDimethylformamide as solvent and graphite as anode material appear to be optimal for this reaction. As mentioned above, the electrochemical oxidation of a diene yields 1,2- and … WebAs mentioned earlier, atomic hydrogen reacts with graphite even at room temperature and this would result in gasification of the carbonaceous solids; a reaction that would produce hydrocarbon products. Since these later gases were not found is an indication that hydrogen was not dissociated and subsequently bonded to the structure.
