“…272, 273 The methyl groups are diastereotopic in both conformers so that at low temperatures there are four N-methyl resonances. Two sets of the methyl groups exchange as the ligand rotations giving rise to two resonances corresponding the average of those above the coordination plane and those below it.…”

Compounds that undergo intramolecular rearrangements at rates that affect the NMR line shapes in generally accessible temperature ranges are described as stereochemically nonrigid. Analysis of 1D and 2D NMR spectra as a function of temperature often allow the rates, as well as the mechanisms of interconversion of conformers or isomers, to be determined. Examples were selected to illustrate the importance of stereochemical nonrigidity in reactivity and the potential for affecting stereochemistry in the products of reactions.

“…An illustrative example is shown in equation (18) (65) shows a process that interconverts a major and minor conformer. 272, 273 The methyl groups are diastereotopic in both conformers so that at low temperatures there are four N-methyl resonances. Two sets of the methyl groups exchange as the ligand rotations giving rise to two resonances corresponding the average of those above the coordination plane and those below it.…”
