Abstract

Borylation of hafno-and zirconocene complexes [(η⁵-C ₅H_2- 1,2,4-Me₃)₂M] ₂(μ₂,η²,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 tBuNC resulted in insertion of the isocyanide ligand into the M-H bonds and furnished the corresponding η²- iminoacylhafnocene complexes.
