“…1). No wave was found at pH 1.5 (Buffer 1) due to the presence of a water wave (7) followed by hydrogen discharge; rapid hydrolysis of the compound in the more alkaline region prevented investigation at pH greater than 10.5 (Buffers 9-11). The first wave is unusually long and drawn out, spanning 3 Detailed tables of the polarographic data are available from the authors.…”

Polarographic reduction of 2-chlorocyclohexanone results in a single pH-independent, diffusion-controlled, irreversible wave, which is due to:carbon-halogen bond fission. The mechanism probably involves formation of a carbanion which reacts rapidly with the solvent to form cyclohexanone. In ammonia buffer of high pH (high NH3 concentration) a second kinetic-controlled wave appears which is apparently largely due to reduction of the imine present in equilibrium with the 2-ketocyclohexanol formed by hydrolysis of the chloroketone; as the first wave due to the chloroketone decreases with time, the second wave increases.Under the conditions of macroscale electrolysis in solution of high ammonia concentration, as in a coulometric experiment, the reduction product of 2-chlorocyclohexanone, cyclohexanone, reacts with ammonia to give cyclohexanonimine, which is in turn reduced to cyclohexylamine. The hydrolysis product of 2-chlorocyclohexanone, 2-ketocyclohexanol, reacts similarly to form 2-iminocyclohexanol, which is presumably reduced to 2-aminocyclohexanol.In connection with the systematic investigation of the electrochemical behavior of halogenated organic compounds (1), 2:chlorocyclohexanone was studied as a typical cyclic haloketone. Its polarographic behavior was investigated from the viewpoints of (a) the relation of half-wave potential, E1/2 , and diffusion current, id, to pH, ionic

“…Measurements in the vicinity of this potential could not be made because of the concurrent or prior discharge of hydrogen ion or the cation of the background electrolyte. No chloroacetone wave was found at pH 1.5 because of the confluence of the wave with a water wave (11) and subsequent hydrogen ion discharge.…”

“…It should also be suitable for solutions containing methacrylonitrile instead of acrylonitrile, since the half-wave potentials of these two compounds differ only by about 50 mv. (11). As sodium, rubidium, and cesium ions exhibit half-wave potentials very close to potassium ion (7) it should be possible to determine acrylonitrile or methacrylonitrile in the presence of any one of these ions when the concentration of the alkali metal ion is known.…”
