Free radical reactions in organic electrode processes—IV : Anodic oxidation of cyanide ions in the presence of aromatic hydrocarbons

Abstract Anodix oxidation of sodium cyanide in methanol has been carried out at a Pt anode in the presence of 1,2,3,4-tetrahydronaphthalene, naphthalene or anthracene. 1,2,3,4-Tetrahydronaphthalene added as organic substrate afforded 6-cyano-1,2,3,4-tetrahydronaphthalene and 1-methoxy-1,2,3,4-tetrahydronaphthalene. In the electrolysis between a Pt anode and a Hg-pool cathode in the presence of naphthalene and anthracene, yielded 1-cyanonaphthalene and 9-cyanoanthracene, respectively. The possible pathways are discussed.

Free radical reactions in organic electrode processes—III : The reaction of aromatic hydrocarbons at platinum anode in acetonitrile solutions containing perchlorate supporting electrolytes☆☆☆

Abstract The electrolysis of certain perchlorates in acetonitrile solutions has been carried out both in the absence and presence of aromatic hydrocarbons, such as toluene and cumene. The products formed indicate that the reactions involve oxidation of the hydrocarbons by perchlorate ions (or radicals). Oxygen-free coupling products of the hydrocarbons were detected, but the extent of these reactions is generally small. Possible reaction paths for the formation of these products are discussed.
