The electrochemical behavior of PdCl2(RNC)2 (1) has been investigated in acetonitrile at Pt and Hg electrodes.The cyclic voltammogram of 1 showed a reduction wave at ca -1.2 V, corresponding to a two-electron transfer.Coulometric reduction of 1 at the Pt electrode gave a binuclear complex, Pd2Cl2(RNC)4 (2).A similar reaction at the Hg electrode gave 2 in a relatively low yield.A Pt electrode was superior to a Hg one in the electrochemical synthesis of 2.The polarogram of 1 at a Hg electrode suggested a CE mechanism of the electrode ration.
