Triethanolamine (TEOA) is one of the most commonly used sacrificial agents in photocatalysis. Due to its more complex structure compared to, for example, ethanol, and its sacrificial role in photocatalysis, it gives a mixture of products. The structures of these molecules are not usually analyzed. Herein, we obtain and isolate the products of TEOA and N-tert-butyl diethanolamine oxygenation under photocatalytic conditions with ≈15 % yield, and followingly characterized them by NMR and mass spectroscopy. The reaction is mediated by potassium poly(heptazine imide) (K-PHI) in the presence of O and affords formyl esters of β-hydroxyethylene formamides from the corresponding ethanolamines.
三乙醇胺（TEOA）是光催化中最常用的牺牲剂之一。与例如乙醇相比，由于其结构更为复杂，以及在光催化中作为牺牲剂的作用，它会产生混合物产物。这些分子的结构通常不进行分析。在此，我们在光催化条件下获得并分离出 TEOA 和 N-叔丁基二乙醇胺的氧化产物，产率约为 15%，并通过 NMR 和质谱对其进行了表征。该反应在 O 的存在下由多聚（六嗪二亚胺）钾（K-PHI）介导，并从相应的乙醇胺中生成β-羟基亚乙基甲酰胺的甲酰酯。
