The electrochemistry of fluorinated β-ketoamines, their sulfur analogues and metal chelates in nonaqueous media

The electrochemistry of eighty fluorinated β-ketoamines, β-thioketoamines, monothio-β-diketones and their complexes of Cu(II) and Ni(II) in dimethylformamide has been investigated. The reduction products of the ligands (LH 2) are found to be unstable anion-radicals; the chemical and electrochemical...

Description
Summary:The electrochemistry of eighty fluorinated β-ketoamines, β-thioketoamines, monothio-β-diketones and their complexes of Cu(II) and Ni(II) in dimethylformamide has been investigated. The reduction products of the ligands (LH 2) are found to be unstable anion-radicals; the chemical and electrochemical transformations of the latter result in the elimination of the F − ion. Metal complexes are characterized by reversible electron transfer. According to ESR data either Ni(I)(LH) 2 or Ni(II)(LH) − 2 are formed as the one-electron reduction products. The dependence of the electrochemical and ESR parameters of complexes on the ligand structure is discussed.
