Oxo incorporated metal acetylide complexes

Studies on organometallic oxo complexes have intensified in recent years due to their implications in catalytic oxidations or as reagents in the oxidation of organic molecules. Synthesis of such complexes containing a hydrocarbon ligand besides the carbonyl and oxo provides an opportunity to obtain complexes with both low oxidation state metal carbonyl fragment and high oxidation state metal oxide fragment in the same molecule. Our attention has been focused on oxo incorporated metal acetylide complexes, in particular, to understand how oxo ligands bond to the metal atoms. Synthetic strategy, structural behavior and reactivity of oxo acetylide metal complexes and clusters are reviewed
