A Kinetic Study of the Fe(III)-Catalyzed Aquation of Bis(malonato)Diaquochromate(III) Ion

The bis(malonato)diaquochromate(III) ion, in acidic solution hydrolyzes to give This reaction is catalyzed by ferric ion and the rate law for this cation catalyzed-aquation in a medium, where Rapid preequilibrium association of basic Cr-bound oxygen with followed by rate-determining ring opening, is proposed to account for the hydrolysis pathway.
