sources. Depending on the substructure considered, this approach does not only represent a significant step forward in practice, with notably higher isotope uptakes, a broader substrate scope and a higher solvent applicability compared to existing procedures, but also the unique way to label important heterocycles using hydrogen isotope exchange. In terms of applications, the high incorporation of deuterium
钌纳米催化可以使用D2或T2气体作为同位素源,对复杂分子中的恶唑,咪唑,三唑和咔唑亚结构提供有效的氘化和tri化作用。根据所考虑的子结构,该方法不仅代表了实践中的重要一步,与现有方法相比,同位素吸收率更高,底物范围更广,溶剂的适用性更高,而且还是使用氢标记重要杂环的独特方法同位素交换。在应用方面,氘原子的高度掺入允许合成用于LC-MS定量的内标。而且,即使在T 2气体低于大气压的情况下,催化剂的功效也允许制备具有高摩尔活性的复杂的放射性标记药物。
