摘要: 报道了六个2—嘧啶氧基苯胺类衍生物的质谱,并利用离子阱质谱的MS~n技术研究了其裂解机理,发现了这一类化合物两个复杂的、独特的重排裂解规律,即通过胺基氢苄基氢向嘧啶环上的氮转移,再发生氢迁移,脱掉羟基自由基得到峰.另外,给出了高分辨质谱数据,以及对化合物c乙酰化物的相关MS图谱加以证实.
英文摘要: The mass spectra of six derivatives. Of 2-pyrimidinoxal aniline were reported. The characteristics and operational principles of the ion trap MS were introduced. The fragmentation pathways were studied using the ion trap MS~n technology. It has been found that there exist two complex but characteristic rearrangements and fragmentation pattems for these compounds. The base peaks of all the derivatives were [M-17]+. And they all yielded the peak of [M-17-90]+. In addition, they had the same fragments such as m/z: 246 and so on. HRMS of compound c and the MS of the acetylation product of compound c proved the fragmentation pathways.
