摘要：

The reversibility of the concerted metalation-deprotonation exchange of eight para-substituted phenyl-pyridines is examined with the parent Cp*RhCl(kappa-C,N-NC5H4-C6H4). Equilibrium constants are determined, and the free energies are used to extract the most important parameters that control the thermodynamics. K-eq values are found to correlate best with heterolytic C-H bond strengths but in a way that is not obvious considering the electrophilic nature of these activations.
