Kinetics of hydrogen isotope exchange reactions. Part XXIII. Isomer distributions in the radiation-induced tritiation of benzene derivatives in aqueous solution

Abstract
The isomer distribution of aromatic tritiation induced by γ-irradiation of solutions of aromatic compounds (anisole, toluene, chlorobenzene, and fluorobenzene) in tritiated water was examined by nitration of the reaction product, separation, and tritium assay of the isomeric mononitration products. In toluene and anisole, ca. 70% of tritium atom attack occurs at ortho-positions; in the two halogenobenzenes the attack appears to be approximately statistical.
