In this paper the electrode kinetics of cathodic reduction of dichloro-bis(triphenyl-phosphine) palladium complex and zinc chloride in DMF was studied. Using electro-chemical techniques we found that the reduction of Pd(PPh_3)_2Cl_2 is irreversible and is charge transfer controlled. The J~0(exchange current) and α(transfer coefficient) were 5.67×10~(-8) A and 0.15 respectively. We also confirmed that the reduction of ZnCl_2 in DMF is diffusion-charge transfer controlled.
