A method for the selective deuteration of polyfunctional organic molecules using catalytic amounts of [RuCl2 (PPh3 )3 ] and D2 O as a deuterium source is presented. Through variation of additives like CuI, KOH, and various amounts of zinc powder, orthogonal chemoselectivities in the deuteration process are observed. Mechanistic investigation indicates the presence of different, defined Ru-complexes
提出了一种使用催化量的 [RuCl2 (PPh3 )3 ] 和 D2 O 作为氘源选择性氘化多官能有机分子的方法。通过改变 CuI、KOH 和不同量的锌粉等添加剂,可以观察到氘化过程中的正交化学选择性。机理研究表明在给定的特定条件下存在不同的、确定的 Ru 配合物。
