Vanadium chemistry

The organometallic chemistry of vanadium has been surveyed in COMC (1982) and COMC (1995).152 153 The chemical and biological importance of vanadium was reviewed in a dedicated edition of Coordination Chemistry Reviews.1 4 Relevant synthetic aspects of vanadium chemistry have also been reviewed,155-158 including early report by Hirao et al. on formation of ketones from organovanadium compounds and acid chlorides.159... 

As seen in the vanadium chemistry (Schemes 46 and 47), activation of isocyanides is one of the key mechanisms in organotantalum chemistry. Scheme 55 generalizes the examples where organotantalum chemistry of isocyanides leads to the formation of products. Although these products remain coordinated to tantalum, these reactions provide insight into the potential for applications to organic synthesis. Methyltantalum species allow formation of... 

The Tp hgands (i.e., tris(pyrazolyl)borates or scorpionates [13]) are close analogs to the Cp hgands (i.e., -cyclopentadienyl), and in connection with the chemistry of the Tp Cr complexes mentioned above, a recent example of O2-binding from vanadium chemistry is of interest, even though it is formally not organometalhc chemistry Reaction of the V(IV) complex... 

Some tribulations in the experimental work and the variety of colours observed in early vanadium chemistry can now be explained as due to the formation of various coordination compounds, early symptoms of a rich and challenging chemistry.
