【摘要】 本文报道了一类以1,4,8,11-十四冠硫醚-4为基本结构的冠硫醚的质谱裂解规律。通过对质谱裂解机理的解析,得到了以碳硫键断裂为特征的质谱图,并归纳出一系列共有的特征碎片离子。阐明这些质谱裂解规律将有助于这类冠硫醚型化合物的结构推断。更多还原

【Abstract】 The mass spectra of a series of crown thioethers such as TTP, TTE, TTX,TTmX, TTPOAc, TTPOBz, TTB, TTPC, BDT and DBTT in which TTP (1, 4, 8,11-tetradecane-crown-thioether-4) was considered as the foundamental skeletonstructure of these compounds have been analyzed. The fragmentation mechanism ofEI mass spectra of these compounds have been observed to be the cleavage of C-Sbond, and the identical characteristic fragmental ions of them were summarizedfrom the data shown in scheme 1 in the Chinese Text. The knowledge of mass spectralbehaviors of these compounds will be helpful in structural elucidation of unknowncompounds of these series.更多还原
