DOIAbstract
The new iron(IV) nitride complex PhB(<sup>i</sup>Pr<sub>2</sub>Im)<sub>3</sub>FeN reacts with 2 equiv of bis(diisopropylamino)cyclopropenylidene (BAC) to provide PhB(<sup>i</sup>Pr<sub>2</sub>Im)<sub>3</sub>Fe(CN)(N<sub>2</sub>)(BAC). This unusual example of a four-electron reaction involves carbon atom transfer from BAC to create a cyanide ligand along with the alkyne <sup>i</sup>Pr<sub>2</sub>N–CC–N<sup>i</sup>Pr<sub>2</sub>. The iron complex is in equilibrium with an N<sub>2</sub>-free species. Further reaction with CO leads to formation of a CO analogue, which can be independently prepared using NaCN as the cyanide source, while reaction with B(C<sub>6</sub>F<sub>5</sub>)<sub>3</sub> provides the cyanoborane derivative
