Ultrafast Electron Diffraction of Transient [Fe(CO)4]: Determination of Molecular Structure and Reaction Pathway

The temporal diffraction–difference approach of the ultrafast electron diffraction (UED) technique was used to determine the molecular structure of the transient [Fe(CO)4] (see picture) formed during the elimination of CO ligands from [Fe(CO)5]. The results clearly show that the major product, up to...

Zusammenfassung:The temporal diffraction–difference approach of the ultrafast electron diffraction (UED) technique was used to determine the molecular structure of the transient [Fe(CO)4] (see picture) formed during the elimination of CO ligands from [Fe(CO)5]. The results clearly show that the major product, up to 200 ps, is the transient [Fe(CO)4] which is formed in the 1A1 state, rather than the ground 3B2 state.
