✦ Synopsis

The kinetics of aquation of cis-[Co(en)z(H20)Br ] 2 + and cis-[Cr(en)2(H20)Br] 2+ (en = ethylenediamine) were investigated in aqueous mixtures of MeOH, EtOH, i-PrOH and t-BuOH. The values of transfer functions corresponding to the transfer of reactants and activated complex from water to the solvent mixtures were evaluated from kinetic measurements and from solubilities of the complex salt. Analysis of the solvent effect confirmed a common Id mechanism for the aquation of the Co in and Cr m complexes.
