Abstract

The magnitude and sign of 1H-31P and 1H-13C coupling constants across the central metal atom (2JX-Rh-H) were measured in a series of octahedral rhodium hydrido phosphine complexes [Rh(PMe3)2(CO)(Cl)(X)H; X = Cl, phenyl (2 isomers)] using a 1H detected, frequency-selective, two-dimensional NMR experiment. The relative and absolute signs of 2J13C-Rh-H, 2J13C-Rh-P, and 2JP-Rh-H were determined, and in the case of 2J13C-Rh-H both the magnitude and sign of the coupling constant were found to depend on the relative disposition of the coupled nuclei about the central metal atom.
