Deuterated homo- and heterocyclic aromatic substrates bearing various functionalities were prepared by isotope exchange in supercritical deuterium oxide, with little or no formation of byproducts. Equilibration was attained rapidly (1 – 24 hrs), and deuterium exchange extended to alpha positions of alkyl homologs. Nitro- and haloarenes, thioethers, telluroethers, and some heterocyclic substrates were
