Study on the reactions of pyridine with fluorine-containing compounds in the gas-phase by electron impact/Fourier transfer ion cyclotron resonance mass spectrometry

The gas-phase ion-molecule reactions of pyridine and fluorine-containing compounds have been studied by the electron impact/Fourier transfer ion cyclotron resonance mass spectrometry (EI/FTICRMS). Comparing the reaction of the standard sample perfluorotributylamine (PFTBA), in the case of 3-oxa-5-iodo-octafluoropentylsulfonyl azide (ICF2CF2OCF2CF2SO2N3), a series of addition–elimination products and loss 28 from the expected adducts were obtained. Possible reaction mechanism was discussed, which was consistent with the results obtained in the condensed phase. These results demonstrated that EI/FTICRMS is a complementary technique for study of the organic reactions.
