Abstract:

Linear sweep voltammetry has been used to study the electrochemical behavior of transition metal structural units Co(PPh3)2Cl2 and Co(PPh3)3Cl in DMF solution with 0.1mol L-1Et4NClO4 on Pt electrode. The results suggest that Co(Ⅱ) is reduced to Co(Ⅰ) at the first step and the process is reversible. The Process of Co(Ⅰ) reduced to Co(0) subsequently is irreversible. The Co(Ⅰ) is not stable in solution and is oxidized easily to Co(Ⅱ).
