✦ Synopsis
Gas
-phase reactions of Mn0,-and MnO,-ions with a series of monofluoro-and pentafluoro-aromatic compounds, i.e. C6H4FX with X = 0-, m-and pCHO and 0-, m-and p-OH and C6F,Y with Y = OH, OCH, , CHO, CN, NO,, COCH, and F, were studied at low pressures by Fourier transform ion cyclotron resonance mass spectrometry. The principal reaction channels identified involve electron transfer from the MnO, -and MnO,ions to the fluorinated aromatic substrates and proton abstraction and nucleophilic displacement of fluorine by these oxometallate ions. The results obtained indicate that in the gas phase Mn0,-is less basic than Mn0,-and that neutral MnO, has a lower electron affinity than MnO, , both values lying between 0.52 and 0.94 eV.
