Cuprous Iodide Description


Copper(I) iodide is the inorganic compound with the formula CuI. It is also known as cuprous iodide. It is useful in a variety of applications ranging from organic synthesis to cloud seeding.
Pure copper(I) iodide is white, but samples are often tan or even, when found in nature as rare mineral marshite, reddish brown, but such color is due to the presence of impurities. It is common for samples of iodide-containing compounds to become discolored due to the facile aerobic oxidation of the iodide anion to molecular iodine.

Cuprous Iodide Uses


Uses 1Cuprous 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,
Uses 2used 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.
Uses 3as a catalyst in many reactions involved in the Grignard reagent, the cuprous iodide can also be in dry Wiff rearrangement reaction.
Uses 4Copper (I) Iodide used in the preparation of alkynyl imines and the synthesis of pyrroles and pyrrole heterocycles. It is also used in the synthesis of BTBT derivatives ([1]Benzothieno[3,2-b]benzothio phene) for use as semiconductors in transistors.
Uses 5A catalyst for N-arylation of amines and amino acids
