Abstract
The cathodic behaviour of the bis(acetylacetonato)nickel(II) complex was investigated in acetonitrile solution by cyclic voltammetry and controlled potential electrolysis. Irrespective of the electrode material employed, this species undergoes a complicated reduction process involving chemical reactions preceding and following the charge transfer step and leading to the formation of metallic nickel as the ultimate product. For this reduction, a mechanistic scheme is proposed which is consistent with the data. Evidence for the formation in the solution of mono(acetylacetonato)nickel(II) and tris(acetylacetonato)nickel(II) complexes were also obtained. © 1985.I documenti in ARCA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
