Mechanism of equilibration of diastereomeric rhenium amide complexes of the formula (.eta.5-C5H5)Re(NO)(PPh3)(NHCHRR'): rhenium versus carbon epimerization Academic Article uri icon

abstract

  • Amide complexes (SR)- and (SS)-(η5-C5H5)-Re(NO)(PPh3)(NHCH(CH3)C6H5) epimerize at rhenium (32‒60 °C) by a mechanism involving initial and rate-determining PPh3 dissociation. Anchimeric assistance of the amide ligand lone pair and an intermediate with a planar, trigonal rhenium are proposed. © 1990, American Chemical Society. All rights reserved.
