The Generation of Neutral Derivatives of Low-Valence Iron, RFe(I), by Netralization—Reionization Mass Spectrometry

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 μs. 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.
