3-取代芳基-2-吲哚基膦酸酯的质谱研究

A Study on Mass Spectrometry of 3-Substitutedaryl-Indolyl-2-Phosphonates

本文报道３－取代芳基－２－吲哚基膦酸酯的质谱研究。发现３－取代芳基－２－吲哚基膦酸酯的膦酰基中的烷基在碎裂过程中也产生γ－烷基重排反应，同时讨论了这类化合物的质谱碎裂行为。

A study on mass spectrometry of 3 - substitutedaryl - indolyl - 2- phosphonates is reported. An γ - alkyl rearrangement of an alkyl group in phosphonate is also found during electron impacting. The fragmentation characteristic of the compounds (BI ) is studied by using electron impact (EI), electron impact - collision activity - mass analysed ion kinetic energy spectrometry (EI - CA - MIKES) and accurate mass measurment techniques(AMMT). The fragmentation pathway is portrayed in a scheme (see fig2).
