A simple method for the synthesis of perdeuterated aromatic hydrocarbons and heterocyclic compounds
A general method has been developed for the preparation of deuterated aromatic compounds that are useful for coal reaction studies and as internal standards for GC/MS analysis. The method requires little specialized equipment or synthesis expertise. A reaction mixture containing Cl, D/sub 2/O, and chromium is used to exchange deuterium for aromatic hydrogens at temperatures of 200/sup 0/ to 300/sup 0/C. A single set of reaction conditions can be used to prepare a wide range of deuterated aromatics with nearly complete exchange of aromatic hydrogen for deuterium and little or no chemical degradation of the reactant. When a 20:1 molar ratio of deuterium to aromatic hydrogen was used the isotopic purity of most species tested.
