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.

Amrollah-Madjdabadi, A.,Beugelmans, R.,Lechevallier, A.
, p. 828 - 830 (2007/10/02)
Aliphatic nitro compounds are easily halogenated by N-chloro- or N-bromosuccinimide in protic solvents to give the practically pure gem-halonitro compounds.
Reaction ofα- Halo Ketones with Nucleophiles

p-Nitro- or p-cyanophenacyl chloride or the 1,1-dimethyl derivatives react with the anion of 2-nitropropane to form the C-alkilation product by a radical chain mechanism (SRN1).With the 1,1-dimethyl derivatives, the free radical substitution is photostimulated and occurs in competition with ionic reactions leading to the oxiranes 5 and hydroxy ketones 6.When K+ is used as the counterion, the SRN1 process is favored by complexation with 18-crown-6. p-Nitro-1,1-dimethylphenacyl chloride gives substitution products with diethyl malonate or diethyl mthylmalonate anions via the SRN1 process, but with PhS- or p-MeC6H4SO2-, substitution occurs by competing ionic and radical processes.Propylacetylenide anion reacts to form the oxirane 13a while diethyl phosphite or thiophosphite anions yield the enol phosphate 14a or thiophosphate 14b. 1,1-Dimethylphenacyl chloride reacts by nonradical processes to give the oxirane with acetylenide anions, the substitution products with PhS- or p-MeC6H4SO2- and a mixture of the enol phosphate, and oxirane 16 with diethyl phosphite anion.With Me2C==NO2-K+, mainly the oxirane is formed in Me2SO but mainly substitution via the SRN1 chain is observed in HMPA.
Reactions of Carbanions with Carbon Tetrachloride in Two-Phase Systems. Chlorinated Products as Nucleophilic and Electrophilic Intermediates
Makosza, M.,Kwast, A.,Kwast, E.,Jonczyk, A.
, p. 3722 - 3727 (2007/10/02)
A variety of carbanions generated in the catalytic two-phase system (aqueous NaOH or K2CO3 and tetrabutylammonium bromide catalyst) react with CCl4 to form chlorinated products that can react as nucleophiles and electrophiles.Thus, chlorinated intermediates generated from arylacetonitriles and propiophenone in the presence of aldehydes and electrophilic alkenes form oxirane and cyclopropane derivatives, respectively.The chlorinated intermediates act as electrophiles toward Cl3C- giving (trichloromethyl)oxiranes (from aryl alkyl ketones), α-trichloromethyl nitriles (from phenyl(dialkylamino)acetonitriles), and benzoyldichloro enamines (from α-dialkylamino ketones).From secondary nitroalkanes both chloronitroalkanes and dinitro compounds can be produced.
