Electrochemical Reduction of the 5,7-Diphenyl-2,3-dihydro-1,4-diazepinium Cation

The 5,7-diphenyl-2,3-dihydro-1,4-diazepinium cation (II), dissolved in dimethylformamide, is reduced in two steps.The first wave, at -1.23 V with respect to an aqueous Ag-AgCl-KCl (saturated) reference, provides a radical which disproportionates to give the corresponding dihydrodiazepine base (I) and a tetrahydrodiazepine (IV).The second wave is at -2.00 V and produces the anion (IV).The reduction was studied by polarography, cyclic voltammetry, and preparative electrochemistry.The dihydrodiazepine base is electroinactive to -2.1 V, whereat it displays an apparently two-electron reduction wave.
