Abstract

The utility of aryltrimethylsilyl derivatives to regiospecifically introduce carrier and no‐carrier‐added quantities of radiobromine and radioiodine into certain aromatic rings has been demonstrated. Using trimethylsilyltoluenes as a model system for aromatic rings that are not highly activated, conditions for the rapid and efficient incorporation of radiobromine and radioiodine were found. Reaction conditions necessary for the radiobrominations were very mild; however, the slower radioiodinations required elevated temperatures or highly acidic conditions.
