hydrogen–deuterium (H/D) exchange reactions of aminobenzoic acids catalysed by NaBD4‐activated Pd/C or RhCl3 with D2O as the deuterium source. We also investigated different NaBD4‐activated metal catalysts (including Pd/C, RhCl3 and Pt/C) under microwave conditions for an efficient H/D exchange of aromatic and heterocyclic compounds. Even higher deuterium incorporations were obtained for Pd/C and Pt/C catalyst mixtures
比较了传统的热条件和微波条件对NaBD 4活化的Pd / C或RhCl 3以D 2 O为氘源催化的氨基苯甲酸的氢-氘(H / D)交换反应。我们还研究了在微波条件下不同的NaBD 4活化金属催化剂(包括Pd / C,RhCl 3和Pt / C),以实现芳香族和杂环化合物的有效H / D交换。由于先前观察到的协同作用,Pd / C和Pt / C催化剂混合物的氘掺入量甚至更高。最后,我们将这些优化条件应用于几种药物活性化合物的MS标准品的一步合成。
