【摘要】 本文对新合成的19个O-乙基-N-异丙基(取代硫脲基)硫代磷酰胺醋进行了质谱研究。讨论了P—N键的断裂,包括简单断裂和重排反应、失HS·反应及硫脲N上不同取代基的影响等问题。在亚稳态测定和高分辨精确质量测量的基础上得到了这类化合物的断裂规律和质谱特征。更多还原

【Abstract】 The mass spectra of a new type of organophosphorus compounds O-ethyl-N-isopropylphos-phoro （thioureido） thioates have been studied using low and high resolution EIMS andB/E, B²/E linked scanning Lechniques. Attention was focused on P-N bond cleavage, whichinvolves simple fragmentations and rearrangement as well as loss of HS, H₂S. The effectsof substituents R″of thioureido on above reactions have been discussed as well.更多还原
