The reaction of carbon monoxide with a β-diketiminato dimethyl niobium complex (BDI)Me2Nb(NtBu) is shown to lead to a variety of products whose distribution displays a remarkable dependence onthe reaction conditions. Among these, the products of metal reduction, enediolate formation, and intramolecular C-H activation have been fully characterized. An investigation into the individual steps leading to these products points to a transient initial monoacyl complex, whose fate may be perturbed via reaction conditions to allow for control over the product distribution. Furthermore, the reaction of (BDI)Me2Nb(NCMe3) with XylNC (Xyl = 2,6-Me2C6H3) yields the η2-ketimine complex (BDI)(Me2C=NXyl)Nb(NCMe3), whose characterization and reactivity enhance our understanding of the sequences involving CO.
