KINETICS, MECHANISM, AND THERMODYNAMIC ASPECTS OF THE INTERCONVERSION OF COMPLEXES OF PLANAR AND NONPLANAR METALLO-AMIDO-N GROUPS.

Article abstract of DOI:10.1021/ja00212a026

In this report we discuss the first mechanistic study of facile isomerizations of diastereomeric complexes in which planar and nonplanar amido-N ligands are interconverted. The accumulated evidence consistently suggests that the T mechanism most reasonably describes the isomerizations of the systems studied. While the focus here has been upon processes occurring at a transition-metal center, the isomerization reactions interconvert cis- alpha and trans diastereomers where the enthalpy difference is primarily a result of the presence of nonplanar amido-N ligands in the former and planar amido-N ligands in the latter.
