Despite their general thermal instability, bis(η5-cyclopentadienyl)diorganozirconium complexes and their hafnium analogues should be capable of undergoing various reactions that bis(η5-cyclopentadienyl)monoorganometal complexes undergo (Section 2.11.4.7). In reality, however, very few such reactions are known. Carbonylation of bis(η5-cyclopentadienyl)diorganozirconium complexes has been studied in detail, but their synthetic scope has so far been limited. One well-documented example is the carbonylation reaction of bis(η5-cyclopentadienyl)dimethylzirconium(IV) (165) to give 166 and 167, which clearly indicates an initial sidewise attack by carbon monoxide, rather than frontal attack, followed by isomerization (Scheme 73).[214]
