The d.c. polarographic reduction of Ni(acac)<SUB>2</SUB> and Ni(hfac)<SUB>2</SUB> was studied in detail in dimethyl sulfoxide. Two kinds of tetraalkylammonium perchlorates and sodium perchlorate were used as supporting electrolytes. Ni(acac)<SUB>2</SUB> gave three waves in all the supporting electrolytes, while Ni(hfac)<SUB>2</SUB> gave two waves in the presence of tetraalkylammonium perchlorate. These waves were explained on the basis of the polarographic properties, molecular weights, and conductivities. The electrode reaction mechanism of Ni(acac)<SUB>2</SUB> can be expressed by:<BR>(<U>Remark: Graphics omitted.</U>)<BR>where the second wave includes a kinetic current. The first wave of Ni(hfac)<SUB>2</SUB> is due to the reduction of Ni(hfac)<SUP>+</SUP> and Ni(hfac)<SUB>2</SUB> themselves; the second wave corresponds to that of free hexafluoroacetylacetonate.
