ABSTRACT:
In processes for the deuteration and/or tritiation of cyclic organic substrates by hydrogen substitution, the substrate is subjected at a temperature of between about 200.degree. and 400.degree. C to the effect of a 0.10% to 10% V/V dilute solution of a strong acid in the respective oxide constituting the isotope pool for the exchange. A deuterated or tritated acid may be used. Rapid exchange in the aromatic ring and high yields are obtained with apparent freedom from side reactions and decomposition.
