ABSTRACT:

Neutralization–reionization mass spectrometry is applied for the generation of low-valence iron derivatives. Neutralization of Rfe⁺ (R=H, F, Cl, Br, I, CN, OH, NH₂, acac, C₆H₅) ions resulted in the corresponding neutrals having lifetimes of at least 5 &mgr;s. Atom connectivities in RFe ions and neutrals were elucidated by a variety of tandem mass spectrometry techniques. The present study provides the first experimental evidence of the intrinsic stability of neutral IFe, NCFe, acacFe and C₆H₅Fe.

Keywords: tandem mass spectrometry, netralization–reionization, organometallics, low-valence iron derivatives
