Thermal and Electrocatalytic Epimerization at Iron as the Chiral Center

Electron-transfer-induced configurational changes at the Fe atom of complexes were first demonstrated by way of examples 1 and 2. Upon reductive inducement with sodium amalgam only the indenyl compound 2 eperimizes; upon oxidative inducement with Cp2FePF6 both complexes epimerize. These electrocatalytic reactions are accelerated enormously compared to the thermal epimerization
