Abstract

The Gibbs energy of reaction of oxidative addition of ammonia to an iridium complex in diethyl ether was calculated by seven density functional methods, in particular B3LYP, PBE, CAM-B3LYP, M05, M06, M06-L, and ωB97X. The calculated free energies, based on geometry optimization and frequency calculations in both the gas phase and solution, were compared with the experimental result, -1.3 kcal mol-1, obtained by Hartwig and coworkers. The M06-L method gives the best result: -1.4 kcal/mol.
