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%)
初级和次级硝基化合物的盐(硝基乙烷、1-和 2-硝基丙烷、硝基环己烷和硝基环庚烷)在过量卤化物、亚硝酸盐、氰化物和苯亚磺酸盐阴离子存在的情况下,在两相中未分开和分开的恒流电解条件下电解介质 (CH2Cl2/H2O) 产生孪生硝基卤化物(35-85% 的产率)、二硝基化合物(15-51%)、腈(6-27%)和硝基砜(50-70%)。仲硝基化合物的盐在未分离的电解条件下与卤化物和苯亚磺酸盐阴离子形成氧化偶联产物。在所有其他情况下,需要分开电解。
