Reactivity of (triphosphine)MoIV‐nitrido complex generated by N2 splitting, toward boranes is reported. The simple adduct Mo≡N→BH3 is observed with BH3.SMe2 while 1,2 addition is evidenced with 9‐BBN leading to H‐Mo=NBR2. A second addition of BH3.SMe2 is facile and forms an unprecedented complex featuring two bridging H between two B and the Mo centers. Addition of PMe3 or BH3.SMe2 promotes reductive elimination and N‐H bond formation. The full sequence of functionalization at Mo≡N obtained after N2 splitting is therefore evidenced in this work.

通过钼氮化物络合物进行 N2 官能化：逐步 BH 键加成。

据报道，通过 N2 裂解产生的（三膦）MoIV-氮化物络合物对硼烷的反应活性。用 BH3.SMe2 观察到简单的加合物 MoeqN→BH3，而用 9-BBN 则证明了 1,2 加成导致 H-Mo=NBR2。 BH3.SMe2 的第二次添加很容易，并形成前所未有的复合物，其特征是两个 B 和 Mo 中心之间有两个桥接 H。添加 PMe3 或 BH3.SMe2 可促进还原消除和 N-H 键形成。因此，本工作证明了 N2 分裂后获得的 MoeqN 官能化的完整序列。
