A Mass Spectrometric Study of Organic Phosphorus Compounds——Ⅴ.EI Spectra of 1,3,2-Oxazaphospholidine 2-Sulfides Derivates

本文报道15种新合成的2-硫-1,3,2-氧氮磷杂环戊烷衍生物的 EI 谱.在质量分析离子动能谱、碰撞诱导分解谱、B/E 联动扫描及高分辨精确质量测量的基础上,讨论了这类化合物的质谱裂解机理及特征.着重讨论上述化合物的氧硫异构现象及几种重排反应.

The mass spectral behaviour of 15 new type of organic phosphorus compounds with aconsiderable insecticidal activity,1,3,2-oxazaphospholidine 2-sulfides derivates,under70 eV electron impact has been studied by means of high and low resolution massspectrometry as well as by B/E linked scan and MIKES/OID analysis.Discussion isfocused into the isomerization between oxygen and sulphur in molecules and somerearrangement reactions.
