 Title    Electrochemistry of Oxygenation Catalysts, Part 6* Electrosynthesis, Structure, Analytical and Electrochemical Properties of Monomeric [Coin(salen)(DMF)2]+ X' Salts (X = PF6, C104)  
 Abstract    Electrochemistry [CoH1(salen)(DMF)2]+ X" salts [X = PF6, C104; salen = bis(salicyliden)ethylendiiminato; DMF = dimethylformamide] have been synthesized by electrochemical and chemical (air) oxidation of Co"(salen). Their monomeric structure with two DMF molecules in the axial positions in both the solid state and DMF solution is shown by X-ray crystal structure analysis, thermal analysis, mass spectroscopy, and 'H and l3C NMR spectroscopy. The electrochemical reduction of the [Coni(salen)(DMF)2]+ cation is investigated by cyclic voltammetry and com­ pared to the oxidation of the neutral CoH(salen). The redox reaction connecting the cobalt(II) and the cobalt(III) species appears to be a quasi-reversible electron transfer. These properties make the [Co1 1 (salen)(DMF)2]+ X-salts starting materials for the analysis of the interaction of basic substrates with cobalt(III) species in the context of the biomimetic oxygenation reactions catalyzed by such complexes.
