Mass Spectra of Sulphur-Containing Heterocycles:Thieno 3,4-d Pyrimidine-2,4-Dione Derivatives

    摘要
  • 摘要: 本文对噻吩骈3,4-d嘧啶-2,4-二酮结构母核在70 eV电子束轰击下质谱的裂解规律进行了研究,并重点讨论了N~1取代基对结构母核裂解规律的影响。实验证明,脂肪烃基取代物的特征碎片为m/z73和68,芳烃基取代的特征碎片为m/z 215。

     

    Abstract: The electron impact induced mass fragmentation of 23 new sulphur-containing heterocycles: Thieno 3,4-d pynmidine-2, 4-dione derivatives are presented. The elucidation of the fragmentation pathways is described. The fragmentation routes have been confirm
