Probing Redox Non‐Innocence in Iron–Carbene Complexes {Fe=C(H)Ar} ^10–11 by ^1,2 H and ¹³ C Pulse Electron Paramagnetic Resonance

https://doi.org/10.1002/anie.202110704

Arnett, Charles H.; Oyala, Paul H.; Agapie, Theodor (November 2021, Angewandte Chemie International Edition)

Abstract We report the synthesis and spectroscopic characterization of a series of iron‐carbene complexes in redox states {Fe=C(H)Ar}^10–11. Pulse EPR studies of the^1,2H and¹³C isotopologues of {Fe=C(H)Ar}¹¹reveal the high covalency of the Fe–carbene bonding, leading to a more even spin distribution than commonly observed for reduced Fischer carbenes.
