摘要： 用XPS表征2-芳胺基-1,3,4-噻二唑-5-硫酮(1)在ω-溴代-ω-(1H-1,2,4-三唑)-苯乙酮诱导下生成的2-芳胺基-3H-1,3,4-噻二唑-5-硫醇类介离子化合物(4).结果表明,化合物4分子中的C1s,N1s,S2p电子结合能均高于化合物1,尤其以N1s,S2p结合能谱最为特征.例如在含3个氮原子的化合物4中由于噻二唑环的两个氮环境不同,故产生3个峰,而在与其结构相近的对照物1中,由于噻二唑环的两个氮环境相近,故产生2个峰.S2p诸状态结合能加合值化合物4均大于化合物1,在化合物4中均是杂环内硫大于杂环外硫.

Abstract: The structures of 2-arylamino-1,3,4-thiadiazolium-5-thiolates(4) were confirmed by Xray photoelectron spectra. The meso ionic were prepared from 2-arylamino 1,3,4-thiadiazol-5-thiones by using ω-bromo-ω-(1H-1,2,4-triazol-1-yl)acetophenone(2). The results showed that the binding energies of C1s, N1s , and S2p in meso-ionic 4 are greater than those in the correspondence compounds 1, which were more obvious in N1s and S2p . For example, N1s showed three signals in mesoionic 4 and only two signals and in compounds 1 because the chemical environment of thiadiazole rings two nitrogen atoms are different in4 and same in1. Furthermore, the additive binding energy of S2p in ring is greater than the exocyclic one for the same mesoionic 4.
