✦ Synopsis

Using an ion trap, we investigated the reactions of [Fe(CloHs)] + with a variety of small molecules L known to be present or close to existing molecules in the interstellar medium. These reactions generally yield stable adducts [Fe(CloHs)L] +. Under visible irradiation, the ligand L is eliminated and the initial complex is restored. The reactions performed with O 2 are of special interest. A spontaneous oxidation is observed, leading to the ejection of an H20 fragment and the formation of a new cationic complex [Fe(CloH60)] +. This complex releases a CO molecule under visible irradiation, indicating that a carbon ring has been attacked. A further oxidation of [Fe(CloH60)] + leads to the formation of a new species [FeC9H502] +. Reasonable assumptions concerning the structure of the different products are proposed.

This paper reports a gas-phase study of ligand effects on the reactivity of the organometallic distonic ion Fe(p-benzyne) Á . New organometallic distonic ions are generated by introducing a benzene ligand onto the metal center of Fe(p-benzyne) Á . We were interested in whether the reactivity of the
