The Pd/C-catalyzed H(2)-D(2) exchange reaction using a H(2)-D(2)O combination provided a general, efficient and environmentally friendly route for the preparation of deuterium gas (D(2)). H(2) sealed in a reaction flask was converted into nearly pure D(2), which could be used for the Pd/C-catalyzed one-pot reductive deuteration of various reducible functionalities and the chemoselective one-pot deuterogenation
使用H(2)-D(2)O组合的Pd / C催化的H(2)-D(2)交换反应为制备氘气(D(2) )。密封在反应烧瓶中的H(2)转化为几乎纯净的D(2),可用于Pd / C催化的各种还原功能的一锅还原氘代和烯烃和乙炔的化学选择性一锅氘代。此外,我们建立了在气球中捕获D(2)的捕获方法,该方法已成功地应用于腈作为烷基化试剂的伯胺的Pd / C催化的还原性单-N-烷基化反应。
