Facile and Convenient Method of Deuterium Gas Generation Using a Pd/C-Catalyzed H2–D2 Exchange Reaction and Its Application to Synthesis of Deuterium-Labeled Compounds
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-catalyzedone-potreductive deuteration of various reducible functionalities and the chemoselective one-pot deuterogenation
