摘要：
It is reported that two kinds of specific mass spectrometric fragmentations are generated from dissociations of the intermediates of both the ion-neutral complex and the proton-bound complex. Collision-induced dissociation, isotopic labelling. and semi-empirical AMI calculations were used to investigate the formation mechanism of the ion of m/z 139 from ionized tetrahydroimidazole-substituted methylene β-diketones and the unimolecular fragmentations pathway of 3-phenyl-1-butyn-3-of upon electron impact.
