The mass spectrometric fragmentation of 2a,4-disubstituted 2,2a,3,4-tetrahydro-2-phenoxy-1H-azeto[2,1-d][1,5]benzothiazepin-1-ones has been investigated using the aid of mass-analyzed ion kinetic energy spectrometry. All compounds tend to eliminate a phenoxy, phenol, and phenoxyketene, respectively, from molecular ions. [M(+)-PhO] ions could also form [M(+)-PhOH] ions, which could further lose alkenes. [M(+)-PhOCH=C=O] ions could further yield 2-arylbenzothiazole ions and other fragment ions.
借助质量分析离子动能光谱法研究了2a,4-二取代的2,2a,3,4-四氢-2-苯氧基-1H-氮杂环丁烷并[2,1-d][1,5]苯并硫氮杂卓-1-酮的质谱裂解。所有化合物倾向于分别从分子离子中消除一个苯氧基、苯酚和苯氧基乙烯酮。[M(+)-PhO]离子也可形成[M(+)-PhOH]离子，后者可进一步失去烯烃。[M(+)-PhOCH=C=O]离子可进一步产生2-芳基苯并噻唑离子和其他碎片离子。
