有机磷化合物的质谱研究 Ⅹ.1,2-二苯基-3,3-二烷基-2,5-二氧-1,4,2-二氮磷杂环戊烷的EI质谱研究

MASS SPECTROMETRIC STUDY ON ORGANICPHORSPHORUS COMPOUNDS Ⅹ.EI MASS SPECTROMETRIC STUDY ON 1,2-DIPHENYL-3,3-DIALKYL-1,4,2-DIAZAPHOSPHOLIDIN-5-ONE-2-OXIDE

应用EI质谱和联动扫描技术研究了13个有机磷杂环化合物,讨论了主要离子的形成过程,分子离子在EI条件下的各种重排反应和取代基对不同解离反应产物离子相对强度的影响。

The EI mass spectra of 13 phorsphorus-containing compounds were reported. The EI spectra of these compounds are characterized by cycle opening cleavage and rearrangement under electron impact conditions. Some rearrangement processes were reported in detail. The substituent effects on fragmentation mechanism of molecular ions were also discussed.
