The iron(IV) imide complexes, (Me2IPr)-R2Fe=NAd (R = neoPe (3a), 1-nor (3b)) undergo migratory insertion to iron(II) amides (Me2IPr)RFe{NR(Ad)} (R = neoPe (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.
