Various mechanistic studies have been carried out on reactions of 5-exo-substituted tricarbonyl(η-cyclohexa-1,3-diene)iron and the tricarbonyl(1-5-η-cyclohexadienylium)iron cation.These have shown that the corresponding endo complexes can be prepared prov

Treatments of (η4-cyclohexa-1,3-diene)Fe(CO)3 complex with 1.2 equivalents of PhMe2SiLi, followed by quenching the reactive intermediate with CF3COOH generated 1-dimethyl(phenyl)silylcyclohex-1-ene and with 2-(p

Attachment of organometaltricarbonyl tags to enzymes is revealed by changes in the vibrational modes of the carbonyl groups. Shoulders on νsym(CO) and νasym(CO) bands in the FTIR spectrum of an organometallic tag derived from tricarbonyl[1-{(2,3,4,5-η)-2,4-cyclohexadien-1-yl}pyridinium]iron(1 + ) hexafluorophosphate(1 - ) were detected on binding to enzymes (α-chymotrypsin, ribonuclease A, alkaline phosphatase and a triacylglycerol lipase). By comparison with tagging reactions between the tricarbonyliron moiety and model compounds, the new spectral features were attributed to an iron complex covalently bonded to the NH2 groups of the amino acid residues of the enzymes. FTIR spectroscopy was used to monitor deprotonation of tagged amino groups on the enzyme surface. Interactions between the organometalcarbonyl tag and other side-chain groups of the amino acid residues were also investigated.
