The reported syntheses of alleged functionalised 1,2,3-triazines from cyclohexane-1,2-dione and aryl azides, in the presence of pyrrolidine and other amines, were repeated. The products do not contain the bicyclic triazine and bicyclic ketone moieties; instead, cyclohexane-fused 4,5-dihydro-1,2,3-triazoles and monocyclic β-ketoamides were obtained, respectively. These corrections are well supported
重复报道的在吡咯烷和其他胺存在下由环己烷-1,2-二酮和芳基叠氮化物合成所谓的官能化的1,2,3-三嗪的过程。该产品不含双环三嗪和双环酮部分;取而代之的是,分别获得了环己烷稠合的4,5-二氢-1,2,3-三唑和单环β-酮酰胺。通过对NMR光谱,IR光谱,元素分析以及与先前已在文献中发表的数据进行仔细分析,很好地支持了这些校正。讨论了用于观察化合物合成的合适机理。
