Acid hydrolysis of organonitriles coordinated to ruthenium(III)

Previous reports have demonstrated that the base hydrolysis of organonitriles is catalyzed by a factor of about 108 on coordination to pentaammineruthenium(III) and by about 106 on coordination to Co(III) and Rh(III). Although not previously reported, there is a base-independent hydrolysis path as well. The reported specific rates of base hydrolysis at 25°C for acetonitrile and benzonitrile coordinated to Ru(III) are 2.2 × 102 and 2.0 × 103 M-1 s-1, respectively. The rates of acid hydrolysis for acetonitrile, benzonitrile, and 1-adamantylcarbonitrile complexes at 25°C are 1.2 × 10-5, 3.4 × 10-5 and 7.2 × 10-6 s-1, respectively. In acid aqueous solution, the hydrolysis reaction rate constant is independent of acid concentration and ionic strength, indicating that the attacking nucleophile is a water molecule. The activation parameters for the acid hydrolysis of pentaammineruthenium(III) complexes of acetonitrile, benzonitrile, and 1-adamantylcarbonitrile (ΔH≠ = 20.0 ± 0.2 kcal mol-1, ΔS≠ = -13.9 ± 0.5 eu, ΔG≠ = 24.1 kcal mol-1; ΔH≠ = 19.0 ± 0.2 kcal/mol-1, ΔS≠ = -15.3 ± 0.5 eu, ΔG≠ = 23.5 kcal/mol-1; ΔH≠ = 21.2 ± 0.3 kcal/mol-1, ΔS≠ = -10.8 ± 1.0 eu, ΔG≠ = 24.4 kcal mol-1, respectively) are very similar, which is consistent with postulation of a similar mechanism for each reaction.
