Rapid and efficient radioiodination of aryl and heteroarylbromides has been achieved using a nickel(0)‐mediated halogen‐exchange reaction. This transformation gives direct access to [123I]‐ and [125I]‐imaging agents for single photon emission computed tomography (SPECT), such as 5‐[123I]‐A85380 (see scheme, Boc=tert‐butyloxycarbonyl, cod=1,5‐cyclooctadiene, TFA=trifluoroacetic acid).
