The kinetics of reactions of palladium(II) acetate with cobalt(II), nickel(II), and copper(II) acetates were studied by spectrophotometry. These reactions produce heterobimetallic complexes Pd-II(mu-OOCMe)(4)M-II(OH2)(HOOCMe)(2), where M = Co, Ni, or Cu. These reactions are very slow in carefully dehydrated (< 0.01% H2O) acetic acid, but are considerably enhanced by water or acetonitrile. Our data indicate that the activation of the kinetically inert ring structure of the initial palladium complex Pd-3(mu-OOCMe)(6) by means of the nucleophilic attack of an H2O or acetonitrile molecule is the key step of the reaction mechanism.
