摘　　要：本文应用低分辨El质谱、高分辨精确质量测量、亚稳分析和不同取代基衍生物方法,研究了二类14种双环笼状磷酸酯的质谱。讨论了化合物的裂解机理和特征碎片。他们都有很强的分子离子峰。A类化合物以M/z179、149为特征碎片,B类以177、147、119为特征碎片。Electron impact mass spectra of organophosphorus compounds containing bicyclic phosphate have been studied by using high resolution mass spectrometry, peak matching exact mass measurement and metastable ion detection techniques. The compounds studied may be classified into two groups: 1-Sxo—4-substituted benzene phosphorothionatc-2, 6, 7-trioxa-1-phosphabicyclo〔2, 2, 2〕octane(class A, n=9)and 1-Oxo-4-substituted formamide-2, 6, 7-trioxa-1-phosphabicyclo〔2, 2, 2〕octane(class B, n=5). All of the compounds of class A and class B show characteristic ions at m/z 179, 149 and 177, 147, 119 respectively.
