摘 要: 利用硫原子上的烷基化反应,合成出5个2,3-双芳基亚氨基-1,4-二硫杂环己烷类化合物,由元素分析、红外光谱分析(IR)1、H核磁共振谱分析(1H NMR)、质谱分析(MS)初步确定化合物的结构,并以单晶X射线衍射分析对其结构进一步确证.研究这5个化合物的电子轰击质谱(EIMS),探讨并归纳其裂解规律,总结该类化合物的EIMS谱特征. Five compounds of 2,3-biarylimino-1,4-dithiacyciohexane were prepared by S-aikylation, the structure of them were analyzed by elemental analysis, IR (infrared), 1H NMR (nuclear magnetic resonance) and MS (mass spectrometry) preliminarily, and further confirmed by X-ray diffraction. The 1H NMR, EIMS (electron impact mass spectrometry) specta of 2,3-biary[imino-l,4-dithiacyc[ohexane were studied in detail. The possible fragmentation mechanism for these compounds was proposed, and the EIMS characteristics of the title compounds have been summarized systematically.
