Abstract
a-Amino acid esters can be added to a carbonyl ligand of [CpFe(CO)3]+CF3SO3 - to give the carbamoyl complexes Cp(OC)(2)Fe-C(O)NHCHRCO2R' (R = H, Me, CH Me2, CH2Ph; R' = Et, Me). This type of reaction may be useful for the marki ng of peptides at the amino end. The crystal structure of Cp(OC)(2)Fe-C(O)N HCH2CO2Et was determined by X-ray diffraction.
