Mass Spectrometry and Gas‐Phase Ion Chemistry of Organomanganese Complexes

Abstract

This review (782 references) represents an exhaustive up‐to‐date survey of literature on mass spectrometry and gas‐phase ion chemistry of organomanganese complexes. Fundamental physico‐chemical characteristics of organomanganese ionic species, as well as the gas‐phase reactions resulting in the dissociation or formation of manganese‐carbon bond(s) are examined. Circa 300 examples of ion/molecule reactions characterizing the reactivity of Mn + , positively or negatively charged manganese clusters, as well as neutrals, cations and anions of various Mn‐containing species (including coordinatively unsaturated ones) are summarized. A variety of studies involving tandem mass spectrometry, neutralization‐reionization mass spectrometry, collision‐induced dissociation, multiple‐photon dissociation, IRMPD spectroscopy and theoretical calculations for organomanganese ion structure characterization are discussed. Additionally, analytical applications of mass spectrometric techniques to the characterization of compounds containing a MnC bond are reviewed. These include a number of relatively simple mononuclear complexes, polynuclear clusters, complexes incorporating organometallic units bridged with organic fragment(s), bifunctional compounds containing organometallic and classical Werner‐type coordination sites, fullerenes or planar polyaromatic hydrocarbons with an organomanganese fragment attached to them, manganospiralenes, manganoscorpionates, supramolecular entities, cymantrene‐peptide bioconjugates, etc.
