Description
Summary:In this article, the complexes [..] (R = ...) are described. A combination of x-ray crystallography, NMR spectroscopy, density functional theory, and "atoms in molecules" calculations unequivocally demonstrates that the complexes contain rare examples of metal... agostic interactions. Moreover, they are fluxional on the NMR time scale, undergoing rapid and reversible ... activation. Kinetic data and calculations point to a bismetallacyclobutane, Rh(V), intermediate.
