ABSTRACT
The second wave thus indicates the electrolytic behavior of a nitrolic acid (XIII). A similar reduction route is found for dihalogenated nitroalkanes such as 1, l-
dichloro-1-nitroethane [42]. This compound shows two polarographic two-electron waves. The second wave does not correspond to the reduction of l-chloro-1-nitroethane, which is the isolated product from a controlled potential reduction (E -0.2V, pH 1) at the potential of the first wave, but rather to a reduction of a chloronitrolic acid, CH3CCI-= N02H. Accordingly, a reduction at the plateau of the second wave (E - I .0V, pH 0.2, t = 5 C) produced chloroacetaldoxime, which was further characterized by its transformation into acetonitriloxide at pH 6.
