The kinetics of the complex formation reaction between Cu(I1) and Fe(II1) aqueous species, present in a 2 M C1- nnedium, and a P-hydroxy oxime (2-hydroxy-5-tert-octylacetophenone oxime) dissolved in toluene has been studied by using a highly stirred apparatus which allows the contribution of interfacial film diffusion processes to the measured rate t,o be assumed equal to zero. The results obtained have indicated that the reactions take place -- at the interface. The following rate laws have been measured: -d[Cu(II)],,/dt - = k~
