on the reaction of phthalaldehyde (OPA) with primary amines. In this contribution, aminoethanol (=kolamin) as a nitrogen‐containing nucleophile was used for the investigation of its reaction mechanism with OPA performed in basic aqueous buffered media (pH 9.5), where an influence of hydration or solvation is expected, and in anhydrous acetonitrile. Depending on the detailed reaction conditions, seven
氨基酸分析和非常有效的消毒程序是基于苯甲醛(OPA)与伯胺的反应。在这一贡献中,氨基乙醇(=可拉明)作为含氮亲核试剂用于研究其在碱性水缓冲介质(pH 9.5)中与OPA的反应机理,该介质预期会发生水合或溶剂化,并在无水情况下产生影响乙腈。根据详细的反应条件,分离出七个产物,并通过NMR,质谱和X射线结构分析确定其结构。提出了反应机理,其中涉及氢化物转移至OPA(Cannizzaro型反应)。
