Borylation of hafno‐ and zirconocene complexes [(η 5 ‐C 5 H 2 ‐1,2,4‐Me 3 ) 2 M] 2 (μ 2 ,η 2 ,η 2 ‐N 2 ), containing strongly activated dinitrogen ligands, with pinacolborane (HBPin) resulted in N–B and M–H bond formation. Treatment of the borylated products with carbon monoxide triggered N–N bond scission with concomitant N–C bond formation to produce μ‐borylimido and μ‐formamidido fragments. Conversely, addition of t BuNC resulted in insertion of the isocyanide ligand into the M–H bonds and furnished the corresponding η 2 ‐iminoacylhafnocene complexes.
