Cuprous iodide CAS  7681-65-4, also known as copper iodide (because the oxidation potential of Cu2+is greater than I -, there is no CuI2), is an inorganic substance with the chemical formula CuI and a molecular weight of 190.45. It is a white or brownish white cubic crystal or dense powder that can easily decompose into a brownish yellow color when exposed to light. It is insoluble in water and ethanol, soluble in concentrated sulfuric acid and hydrochloric acid, and also soluble in liquid ammonia, potassium iodide, and potassium cyanide solutions. React with sodium hydroxide to produce cuprous oxide, sodium iodide, and water.

Used as an organic reaction catalyst, anode ray tube cover, animal feed additive, etc. Density 5.63g/mL, melting point 605 ℃, boiling point 1336 ℃. It exists in the form of copper iodide in nature.

Main purpose

It can be used as an organic synthesis catalyst, resin modifier, artificial rainfall agent, anode ray tube cover, and as a source of iodine in iodized salts. In the presence of 1,2- or 1,3-diamine ligands, cuprous iodide can catalyze the conversion of brominated aromatic hydrocarbons, brominated heterocyclic compounds, and vinyl bromide to corresponding iodides. The reaction is generally carried out in a dioxane solvent, using sodium iodide as the iodization reagent.

Aromatic iodides are generally more active than corresponding chlorides and iodides, therefore, cuprous iodide can catalyze a series of coupling reactions involving halogenated hydrocarbons, such as Heck reaction, Stille reaction, Suzuki reaction, and Ullmann reaction. 2-Bromo-1-octen-3-ol undergoes a coupling reaction with 1-nonyne in the presence of dichlorobis (triphenylphosphine) palladium (II), cuprous chloride, and diethylamine to produce 7-methylene-8-hexadecan-6-ol.
