摘要： There is provided a method for deuterating an aromatic compound having aromatic hydrogens. The method includes the steps: (a) providing a liquid composition including deuterium oxide having dissolved or dispersed therein the aromatic compound and a transition metal catalyst; and (b) heating the liquid composition at a temperature of 120° C. or greater, and a pressure of 50 psi or greater, for a period of 24 hours or less, to form a deuterated aromatic compound.
