摘要
Different negative fragmentations of synthesized polyamides containing N-methylpyrrole and N-methylimidazole were analyzed by electrospray ionization tandem mass spectrometry with low-energy collision-induced dissociation. An interesting rearrangement derived from amino catalysis of N-methylimidazole was observed. The observation is useful for the study of the correlations between the sequences of polyamides and their mass fragmentation pathways. Copyright (c) 2006 John Wiley & Sons, Ltd.
