The polarographic reduction of dichloromalononitrile in acetonitrile produced one polarographic wave ( at 0°C vs. reference electrode). A plot of vs. produced a 1‐electron reduction for the rate‐controlling step. A postulated mechanism suggested a dicyanocarbene, and a large‐scale potentiostatic reduction with tetramethylethylene as the trapping agent produced the adduct of dicyanocarbene, 1,1‐dicyano‐2,2,3,3‐tetramethylcyclopropane. The yield of the cyclopropane adduct was less than 1%, and was identified by chromatographing the reduction mixture on two different SCOT columns, OV‐101 and OV‐17. Dicyanocarbene has been prepared previously by debromination of dibromomalonitrile and dehydrobromination of bromomalononitrile, but this is the first reported generation of dicyanocarbene via electrochemical processes.
