The treatment of a variety of heterocyclic thiones with hydrogen peroxide in acetic acid produces either heteroaromatic cations or the corresponding "oxo" compound. The results may be correlated with structural and electronic features. Benzo substitution or the presence of strongly electron withdrawing groups in the molecule favors the latter product, whereas the presence of a σ trivalent nitrogen atom in the molecule favors the former.
将各种杂环硫醚与过氧化氢在醋酸中处理,会产生杂芳阳离子或相应的“氧化”化合物。结果可能与结构和电子特性相关。苯基取代物或分子中强电子抽提基团的存在有利于后者产物的生成,而分子中存在σ三价氮原子有利于前者的生成。
