- Electrooxidative coupling of salts of nitro compounds with halide, nitrite, cyanide, and phenylsulfinate anions
-
Electrolysis of salts of primary and secondary nitro compounds (nitroethane, 1- and 2-nitropropanes, nitrocyclohexane, and nitrocycloheptane) in the presence of excess halide, nitrite, cyanide, and phenylsulfinate anions under undivided and divided amperostatic electrolysis conditions in a two-phase medium (CH2Cl2/H2O) produces geminal nitrohalides (35-85% yields), dinitro compounds (15-51%), nitronitriles (6-27%), and nitrosulfones (50-70%). The salts of secondary nitro compounds form the products of oxidative coupling with halide and phenylsulfinate anions under the undivided electrolysis conditions. In all other cases, divided electrolysis is required.

- Catalyzed Oxidative Nitration of Nitronate Salts
-
Nitronate salts are converted to gem-dinitro compounds with nitrite ion and persulfate, in the presence of a catalytic amount of ferricyanide.The use of cyanide or sulfinate salts in place of nitrile gave gem-cyanonitro compounds and α-nitro sulfones, respectively.

- Oxidative Substitution of Nitroparaffin Salts
-
α,α-Dinitro compounds, α-nitro sulfones, and α-nitro nitriles are obtained in excellent yields when nitroparaffin salts are coupled to nitrite, benzenesulfinate, and cyanide ions by the agency of potassium ferricyanide.
