A method of deuteration in which a compound with aromatic ring and/or heterocycle having an enhanced deuteration ratio can be obtained. There is provided a method of deuterating a compound with aromatic ring and/or heterocycle, characterized in that a compound with aromatic ring and/or heterocycle is reacted with a deuterium source in the presence of an activated mixed catalyst composed of at least two members selected from among a palladium catalyst, a platinum catalyst, a rhodium catalyst, an iridium catalyst, a ruthenium catalyst, a nickel catalyst and a cobalt catalyst.

Procédé de deutération permettant d'obtenir un composé à noyau aromatique et/ou hétérocycle aromatique qui présente un rapport de deutération accru. L'invention concerne un procédé de deutération d'un composé à noyau aromatique et/ou hétérocycle aromatique, caractérisé par la mise en réaction d'un composé à noyau aromatique et/ou hétérocycle aromatique avec une source de deutérium, en présence d'un catalyseur mixte activé qui se compose d'au moins deux éléments, sélectionnés dans le groupe comprenant un catalyseur de palladium, un catalyseur de platine, un catalyseur de rhodium, un catalyseur d'iridium, un catalyseur de ruthénium, un catalyseur de nickel et un catalyseur de cobalt.
