The alkaline hydrolysis of cisand rrans-diacetatobis(l,2-propanediamine)cobalt(III) cations appears to follow a substitution nucleophilic unimolecular conjugate base mechanism.
In these cations, the acetate ligands are replaced by hydroxide ion in a stepwise manner. Both isomers undergo complete hydrolysis without configurational change.

Following the kinetic investigation of the solvolysis of a range of cobalt(II1) complexes in mixtures of water + cosolvent where the cosolvent enhances the solvent structure and decreases the dielectric constant, kinetic data are now reported for such a solvolysis in water + urea where urea acts as
Rate constants for base hydrolysis of the trzs-( 1,lO-phenanthroline)iron(II) cation and for solvolysis of the cis-dichlorobis(l,2-ethanediamine)cobalt(III~ cation have been measured in binary aqueous mixtures containing l,a-ethanediol, 1,2or 1,4-butanediol, 1,2-or 1,6-hexanediol, 1-propanol, or t-b
