Uses | 1. Cuprous iodide is so widely used as catalyst in organic synthesis, resin modifier, artificial rainfall agents, cathode ray tube cover, as well as sources of iodine in iodized salt. In the presence of 1,2-or 1,3-diamine ligand, cuprous iodide can catalyze reaction of aryl bromide, vinyl bromide and brominated heterocyclic compound converting to the corresponding iodide. The reaction is generally in dioxane solvent, and sodium iodide is used as iodide reagents. Aromatic iodide general is more lively than the corresponding chloride and iodide, therefore, iodide can catalyze a series of reactions involved in coupling a halogenated hydrocarbon, for example, Heck reaction, Stille reaction, Suzuki reaction and the Ullmann reaction. In the present of dichloro bis (triphenylphosphine) palladium (II), cuprous chloride and diethylamine, 2-bromo-1-octen-3-ol with 1-Nonyl acetylene coupling reaction to produce 7-sub-8-hexadecene-6-ol. 2. used as a catalyst for organic reactions, cathode ray tube covering, also used as animal feed additives, etc. copper iodide and mercuric iodide may also be used together as the indicator of measuring rising temperature of mechanical bearing. 3. as a catalyst in many reactions involved in the Grignard reagent, the cuprous iodide can also be in dry Wiff rearrangement reaction. |
