Novel, substituted benzamides in radioiodinated form are useful in radiopharmaceutical compositions in nuclear medicine as imaging agents to detect, visualize and analyze the, distribution and function of the dopamine D-2 receptor in the mammalian brain. The substituted benzamides and their racemic mixtures or their optically resolved enantiomers can be made by reacting a trialyltin substituted benzamide with an acid in the presence of radioactive iodine, generated by in situ oxidation of an appropriate iodide nuclide salt.
