本文报道了7种新的N-烷基-N′-乙氧羰基甲基-N′-芳磺酰基-O-乙基磷酰二胺酯化合物的电子轰击质谱(EIMS)和化学电离质谱(CIMS,甲烷为反应气)。结果表明,无论是EIMS,还是CIMS均存在较多的骨架重排离子峰;取代基对谱图有较大的影响;EIMS中P—N键的断裂为重要质谱特征,CIMS中MH~+准分子离子为重要特征离子,还存在分子离子反应的产物。
In this paper, the electron impact mass spectra (EIMS) and chemical ionization mass spectrometry (ESIMS) of seven new N-alkyl-N’-ethoxycarbonylmethyl-N’-arylsulfonyl- CIMS, methane is the reaction gas). The results showed that there were more skeleton rearrangement ion peaks in both EIMS and CIMS; the substituents had a greater influence on the spectra; the breakage of P-N bonds in EIMS was an important mass spectral feature; Molecular ions are important characteristic ions, but also the product of molecular ion reaction.
