Thermolysis of the iron(IV) nitride complex [PhB( t BuIm) 3 FeN] with styrene leads to formation of the high‐spin iron(II) aziridino complex [PhB( t BuIm) 3 Fe‐N(CH 2 CHPh)]. Similar aziridination occurs with both electron‐rich and electron‐poor styrenes, while bulky styrenes hinder the reaction. The aziridino complex [PhB( t BuIm) 3 Fe‐N(CH 2 CHPh)] acts as a nitride synthon, reacting with electron‐poor styrenes to generate their corresponding aziridino complexes, that is, aziridine cross‐metathesis. Reaction of [PhB( t BuIm) 3 Fe‐N(CH 2 CHPh)] with Me 3 SiCl releases the N‐functionalized aziridine Me 3 SiN(CH 2 CHPh) while simultaneously generating [PhB( t BuIm) 3 FeCl]. This closes a synthetic cycle for styrene azirdination by a nitride complex. While the less hindered iron(IV) nitride complex [PhB(MesIm) 3 FeN] reacts with styrenes below room temperature, only bulky styrenes lead to tractable aziridino products.
