  A method for producing a compound having a deuterated aromatic ring or heterocyclic ring according to the invention includes heating a compound having an aromatic ring or heterocyclic ring in the presence of heavy water, a transition metal and a metal which generates deuterium. As the metal which generates deuterium, at least one metal selected from the group consisting of aluminum, magnesium, zinc, iron, lead and tin is preferred. As the transition metal, at least one metal selected from the group consisting of platinum, palladium, ruthenium and rhodium is preferred. The heating is preferably carried out by microwave irradiation.

  根据本发明，生产具有氘代芳香环或杂环的化合物的方法包括在重水、过渡金属和产生氘的金属存在下加热具有芳香环或杂环的化合物。作为产生氘的金属，优选铝、镁、锌、铁、铅和锡中的至少一种金属。作为过渡金属，优选铂、钯、钌和铑中的至少一种金属。加热最好通过微波辐射进行。

  An effective and applicable Pt/C-catalyzed deuteration method of aromatic rings using D2O as a deuterium source under hydrogen atmosphere was developed. Five percent Pt/C would lead to quite effective H-D exchange results on the aromatic ring systems. The reaction is general for a variety of aromatic compounds including biologically active compounds.

  An effective and applicable deuteration method for aromatic rings using Pt/C–D2O–H2 system was established. Especially, phenol was fully deuterated even at room temperature, and other electron-rich aromatic nuclei were efficiently deuterated under mild conditions. The scope and limitations of the presence method and its application to the synthesis of deuterium-labeled biologically active compounds and deuterium-labeled building blocks for practical multi-gram scale syntheses are reported.
