Abstract

The reductions of nitrobenzene and 4-nitrophenol were studied by cyclic voltammetry in the room temperature ionic liquid 1-butyl2,3-dimethylimidazolium bis(trifluoromethylsulfonyl)imide [C(4)dmim][N(Tf)(2)] on a gold microelectrode. Nitrobenzene was reduced reversibly by one electron and further by two electrons in a chemically irreversible step. The more complicated reduction of 4-nitrophenol revealed three reductive peaks (two irreversible and one reversible) which were successfully simulated using the digital simulation program DigiSim((R)) using a mechanism of rapid self-protonation, given below.
