Electrochemical Properties of Poly cyclic Compounds Studied by the Polarographic Method in Anhydrous Systems 111. Polarographie Reduction Potentials of Carcinogenic Nitrogen Compounds in Dimethylsulfoxide

The Polarographie reduction of a series carcinogenic and noncarcinogonic polycyclic nitrogen compounds in anhydrous dimetbylsulfoxidc containing tetrabuthylammonium Perchlorate as supporting electrolyte has been studied. The obtained results were compared with the number or with the position of nitrogen atoms in the molecules and with their carcinogenic activity. The values of half-waves potentials generally confirmed the mechanism proposed for the reduction of aromatic polycyclic carcinogenic hydrocarbons based on the Polarographie experiments in dimethylsulfoxide. Agreement of the obtained results with the data reported by Polarographie study in anhydrous dimothylformamide indicates, that the Polarographie behavior of polycyclic nitrogen compounds in dimethylsulfoxide is very similar.
