原始语种摘要: Abstract(#br)The electrochemical oxidation of 2-amino dithiocarboxylic acid (ACDA) and its nickel(II) complex has been studied in DMF at a platinum electrode. The oxidation of the ligand shows two oxidation peaks (+0.8 V and +1.1 V). The first oxidation peak is related to ring formation between two dithio groups with the elimination of one sulphur atom via two electron processes. The second peak is due to a two-electron transfer process by releasing a proton. The oxidation of the Ni(II) complex of ACDA, Ni(ACD) 2 , is usually irreversible and metal-based on a short time scale while on a long time scale a ligand-based oxidation predominates. Although the formally nickel(III) species could not be prepared and isolated chemically, they are readily formed from Ni(ACD) 2 and the...
