氮杂环化合物的质谱研究(Ⅱ)——N-取代1,2,3-苯并三唑异构体的电子电离质谱

Mass Spectrometric Research on Nitrogen-Containning Heterocycles(Ⅱ)——the EI Mass Spectra of N-Substituted 1, 2, 3-Benzotriazollc Isomers

摘要: 本文报道十二个合成的N-取代1,2,3-苯并三唑化合物的EI质谱,并讨论其N-1-和N-2-取代异构体的裂解特点。这些异构体包括N-1-和M-2-烷基(≥C_4H_9)-、苄基-、烯丙基-苯并三唑以及苯并三唑基乙酸乙酯。

Abstract: The EI mass spectra of twelve synthetic N-substituted 1, 2, 3-benzotria-zoles have been reported. The fragmentation characters of their N-1-and N-2-substituted isomers have also been discussed. These isomers involve N-1-andN-2-alkyl (≥C_4H_9)-, benzyl-and allyl-benzotriazoles, and benzotriazolylethylacetate.
