Over the past three decades gas-phase catalytic cycles involving metal ions, complexes or clusters as intermediates have been discovered using either multistage mass spectrometry based experiments in trapping instruments or via flow tube methods. These studies have their foundations in: (i) the development of ion cyclotron and quadrupole ion trap mass spectrometers and the flowing afterglow technique, which date back to the 1960s; (ii) the development of ionization methods that allow the formation of gas phase metal ions, including electrospray ionization. Selected examples are reviewed that highlight the range of reaction types that are catalyzed in these processes, including: (i) oxidation of inorganic and organic substrates; (ii) decomposition of acetic acid via either water loss or decarboxylation channels (protodecarboxylation); (iii) decarboxylative C-C bond coupling reactions; and (iv) the dehydrogenation and trimerisation of ethylene to form benzene.
