Aryl iodides
Synthetic aryl iodides are used as X-ray contrast agents, but otherwise these compounds are not produced on a large scale. Aryl iodides are "easy" substrates for many reactions such as cross-coupling reactions and conversion to Grignard reagents, but they are much more expensive than the lighter, less reactive aryl chlorides and bromides.
