Cuprous iodide Chemical Properties,Uses,Production
Chemical Properties
Cuprous Iodide, Cu2O, cubic white crystals, practically insoluble in H2O or alcohol, soluble in NH4OH, potassium iodide, or potassium cyanide. Used in Sandmeyer’s reaction to synthesize aryl chlorides.
Uses
Copper (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.
General Description
Odorless tan or off-white solid. Sinks in water. 
Marshite, CuI, octahedral crystals to 4 mm
Reactivity Profile
Cuprous iodide has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.
Hazard
Toxic.
Health Hazard
Inhalation causes irritation of nose and throat. Ingestion of copper salts produces violent vomiting and purging, intense pain, collapse, coma, convulsions, and paralysis. Contact with eyes or skin causes irritation.
Fire Hazard
Special Hazards of Combustion Products: Irritating hydrogen iodide or iodine vapors may form in fire.
Purification Methods
It can be freshly prepared by dissolving an appropriate quantity of CuI in boiling saturated aqueous NaI over 30minutes. Pure CuI is obtained by cooling and diluting the solution with water, followed by filtering and washing sequentially with H2O, EtOH, EtOAc, Et2O and pentane, then drying in vacuo for 24hours [Dieter, J Am Chem Soc 107 4679 1985]. Alternatively wash it with H2O, then EtOH and finally with Et2O containing a little iodine. Traces of H2O are best removed first by heating at 110o and then at 400o. Exess of I2 is removed completely at 400o. It dissolves in Et2O if an amine is present to form the amine complex. On heating it becomes red, then black, but changes to white on cooling. It is sparingly soluble in H2O or alkali iodide solutions but readily soluble in NH3 (which absorbs CO) and in cyanide or thiosulfate solutions.
