Terminal iron imido complexes with highly electron-withdrawing N-substituents have remained elusive despite their proposed implication in N-group-transfer chemistry. In a recent issue of Cell Reports Physical Science, Deng and co-workers report the isolation and characterization of an N-trifluoromethyl-substituted Fe(IV) bis-imido species that displays a triplet ground state and undergoes intramolecular C‒H activation.

走向理解高吸电子末端 Fe(IV) 酰亚胺

具有高度吸电子N取代基的末端亚胺铁配合物仍然难以捉摸，尽管它们暗示了N基团转移化学。在最近一期的Cell Reports Physical Science 中，Deng 及其同事报道了一种N-三氟甲基取代的 Fe(IV) 双亚氨基物质的分离和表征，该物质显示出三重基态并经历分子内 C-H 活化。
