Abstract
Mass spectrometric decomposition of ZnCl2 complexes of anabasine (neonicotine), nicotine and its chalcogens (O, S, Se) was investigated by positive-ion electrospray ionization. The most abundant product ions for all complexes correspond to the protonated molecule of alkaloid. The proposed fragmentation pathways in the ESI spectra of complexes with nicotine, neonicotine (structural isomer of nicotine) and cotinine is slightly different from that proposed for complexes of thionicotine and selenonicotine. Moreover, the EI MS and ESI MS mass spectra of selenonicotine are also discussed and general fragmentation routes of its molecular ions are proposed.
