【摘要】 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。更多还原

【Abstract】 The electron impact mass spectra (EIMS) and chemical ionization mass spectra (CIMS) of seven new N-alkyl-N’ -ethoxycarbonylmethyl-N’ -arylsulfonyl-O-ethyl phosphorodia-midoates are reported. The results show the EIMS and CIMS of this type compound all have many ion peaks produced through skeleton rearrangements. The difference of substituents has an effect on the mass spectra. P-N bond cleavage is important mass spectra behaviour in EIMS. MH+ ions have higher relative intensity in CIMS case. There are many products from ion-molecular reaction.更多还原
