The iron(IV) imide complexes, (MeIPr)-RFe=NAd (R = Pe (3a), 1-nor (3b)) undergo migratory insertion to iron(II) amides (MeIPr)RFe{NR(Ad)} (R = Pe (4a), 1-nor (4b)) without evidence of imidyl or free nitrene character. By increasing the field strength about iron, odd-electron reactivity was circumvented via increased covalency.
铁(IV)亚胺配合物(MeIPr)-RFe=NAd（R=Pe（3a），1-降冰片（3b））经历迁移插入到铁(II)酰胺(MeIPr)RFe{NR(Ad)}（R=Pe（4a），1-降冰片（4b））中，没有亚氨基或游离氮烯特征的证据。通过增加铁的场强，增加了共价性，从而避免了奇数电子反应性。
