摘要：

The mass spectrometric behaviour of five polydentate Schiff bases derived from the condensation of formyl or diformyl precursors (2,3-dihydroxybenzaldehyde, 2-hydroxy-3-methoxybenzaldehyde, 4-methyl-2,6-diformylphenol, 2,6-diformylpyridine or 2,2-(ethylenedioxy) dibenzaldehyde with 4-amino-benzo-5-crown-5 has been investigated by fast atom bombardment and metastable ion studies The mass spectra mainly exhibit the results of decomposition processes related to the crown moiety. only for two compounds have cleavages of the aldimine group been demonstrated. This behaviour is explained either by protonation on specific sites or by the occurrence of resonance phenomena.
