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。

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 EIMSand CIMSof this type compound all have many ion peaks produced through skeleton rearrangements.The difference of substituents has an effect on the mass spectra.P-Nbond 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.

Key words: EIMS, CIMS, Skeleton rearrangement, Substitution effect, Phosphorodiamidoates
