Description

It is used as a catalyst in organic synthesis, cathode ray tube coating, cloud seeding, and as temperature indicator with HgI. It catalyzes the conversion of aryl, heteroaryl, and vinyl bromides into the corresponding iodides, which are employed in coupling reactions such as Suzuki, Stille, Sonogashira, Heck and Ullmann reactions.
