4,6-二取代-3-酮-5-硫酮-1,2,4-三嗪类化合物的质谱研究

A Study of Mass Spectra of 4,6-Disubstituted-3-one-5-thione-1,2,4-triazine Compounds

1,2,4-三嗪类化合物具有抗癌、抗病毒、杀虫、抑制中枢神经系统等多种作用。前文用苯甲酰基硫代甲酰胺直接与氨基脲反应,制备了8种新的4,6-二取代-3-酮-5-硫酮-1,2,4-三嗪类化合物(a—h),本文测定了其电子轰击质谱、高分辨质谱及联动扫描质谱,以了解其质谱裂解途径。

The El mass spectra of eight new 4, 6-disubstituted-3-one-5-thione-1, 2, 4-triazine compounds are reported. Their mass spectral fragmentations are proposed on the basis of high resolution MS and the B/E linked scan spectra.
