相当于N的新型氮化铁(IV)配合物PhB-((i)Pr(2)Im)(3)Fe与2当量的双(二异丙氨基)亚环丙烯(BAC)反应，得到PhB-((i)Pr(2)Im)(3)Fe(CN)(N-2)(BAC)。这个不寻常的四电子反应例子涉及碳原子从 BAC 转移以产生氰化物配体以及相当于 C-(NPr2)-Pr-i 的炔烃 (Pr2N)-Pr-i-C。铁配合物与不含 N-2 的物质处于平衡状态。与CO的进一步反应导致形成CO类似物，其可以使用NaCN作为氰化物源独立制备，而与B(C6F5)(3)反应则提供氰基硼烷衍生物。
The new iron(IV) nitride complex PhB-((i)Pr(2)Im)(3)Fe equivalent to N reacts with 2 equiv of bis(diisopropylamino)cyclopropenylidene (BAC) to provide PhB-((i)Pr(2)Im)(3)Fe(CN)(N-2)(BAC). This unusual example of a four-electron reaction involves carbon atom transfer from BAC to create a cyanide ligand along with the alkyne (Pr2N)-Pr-i-C equivalent to C-(NPr2)-Pr-i. The iron complex is in equilibrium with an N-2-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(C6F5)(3) provides the cyanoborane derivative.
