A series of deuterated 1,2,3-triazoles bearing various substituents were produced by hydrogen–deuterium exchange reactions of pre-synthesized original 1,2,3-triazoles, giving high level of deuteration and high yields. The catalytic system was successfully extended to the dehalogenation and halogen–deuterium exchange procedures of iodo-functionalized 1,2,3-triazolyl derivatives. This study forms a promising
利用以DMSO- d 6为氘源的碱催化,开发了一种高效便捷的氘标记的1,2,3-三唑。通过预先合成的原始1,2,3-三唑的氢-氘交换反应,可以制得一系列带有各种取代基的氘代1,2,3-三唑,具有很高的氘化率和高收率。催化系统已成功扩展到碘官能化的1,2,3-三唑基衍生物的脱卤和卤素-氘交换过程。这项研究为未来开发含1,2,3-三唑基的有机衍生物,聚合物材料和生物医学分子奠定了有希望的基础。
