苯并二吡喃二酮类化合物的质谱学研究

Mass Spectra of 2,8—Substituted—Aryl—Benzo—(1,2—b:5,4—b')Dipyran—4,6—Dione

摘要: 本文报道使用低分辨及高分辨电子轰击质谱(EIMS)和电子轰击—碰撞活化—质量分析离子动能谱(EI—CA—MIKES)测定十个2,8—取代芳基苯并(1,2—b:5,4—b’)二吡喃—4,6—二酮类化合物。对这类化合物的质谱裂解方式进行了讨论,并与典型黄酮化合物的质谱裂解规律进行了比较。此类化合物的质谱学研究在文献中尚未见报道。

Abstract: Ten 2,8-Substituted-Aryl-Benzo-(1, 2-b: 5, 4-b')Dipyran-4, 6-Diones were determined by EI、HREI and EI-CA-MIKES (collision activated mass-analyzed ion kenetic energy spectrum). Their main fragmentations in mass spectrometry were discussed in comparasion with that of typical flavonoids. The mass spectra of these compounds have not appeared in the literature before.
