Half sandwich compounds are organometallic complexes that feature a cyclic polyhapto ligand bound to an MLn center, where L is a unidentate ligand. Thousands of such complexes are known. Well-known examples include cyclobutadieneiron tricarbonyl and (C5H5)TiCl3. Commercially useful examples include (C5H5)Co(CO)2, which is used in the synthesis of substituted pyridines, and methylcyclopentadienyl manganese tricarbonyl, an antiknock agent in petrol. * MMT is a commercially useful antiknock compound. * CpCo(CO)2 is a catalyst for the synthesis of pyridines. * (C4H4)Fe(CO)3. * * * *
