The reaction proceeds with the stepwise formation of monoaqua and diaqua products. Only the formation of the monoaqua intermediate was followed as this species could not be obtained in a pure state. Aquation proceeds through a dissociative process. The second order rate constants are 11.8 (25°), 17.5 (30°); 30.0 (35°) l mol−1 s−1. Activation parameters are ΔH‡ 52±3 kJ mol−1; ΔS‡−108±8 JK−1 mol−1.
