Pteroylglutamic acid was labeled with deuterium by trifluoroacetic acid-catalyzed exchange with deuterium oxide. The product, pteroylglutamic acid-3',5'-H2, was selectively labeled with deuterium in the 4-aminobenzoyl portion of the molecule; there was no evidence for isotope incorporation at C or

## Abstract 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
