• Six bis(dimethylphenyl) analogues of dithizone are prepared, characterized and their reactions with metal ions in a two phase system are reported. The extraction equilibria of their complexes with Cd(II), Co(II), Hg(II), Pb(II), Tl(I), Zn(II), and Bi(III) as well as their spectral characteristics are described. Complete extraction of these metal chelates requires higher pH's than those needed for the unsubstituted dithizone. The molar absorptivities of Bi(III) complexes with bis(3,4-dimethylphenyl)-, and bis(3,5-dimethylphenyl) analogues are higher than the corresponding value of Bi(III) dithizonate. The molar absorptivities of Cu(II) and Hg(II) (in CCl<SUB>4</SUB>) complexes with bis(3,5-dimethylphenyl) analogue are also higher than the corresponding values of the unsubstituted dithizone complexes.
