An unusually diverse array of products formed upon carbonylation of a dialkylniobium complex

The carbonylation reaction of the dimethylniobium complex (BDI)[Me.sub.2]Nb([N.sup.t]Bu) (BDI = [beta]-diketiminate) is described. The results have shown an ability to dial in specific product mixture based on very subtle modifications to the reaction conditions, however the close proximity of diverse reaction pathways for second-row transition metals have impeded the progress in these areas.
