Currently, the most important and common use of organoiodine compounds involves various metal-mediated cross-coupling reactions where they serve as premier electrophilic partners in Heck, Negishi, Suzuki, Sonogashira, Stille, and similar cross-coupling protocols. These metal-catalyzed cross-coupling reactions are extensively employed in preparative organic chemistry, the synthesis of complex natural products, and the manufacture of drugs, as well as in supramolecular and materials chemistry.
