Description and Uses
Cuprous iodide is used in the preparation of alkynyl imines, which are crucial intermediates for the synthesis of pyrroles and pyrrole heterocycles. It plays a role in the synthesis of BTBT derivatives, specifically benzothieno[3,2-b]benzothiophene, which are semiconductors used in transistors. Beyond its synthetic utility, copper (I) iodide serves as a catalyst for N-arylation of amines and amino acids, facilitating organic reactions. It also has practical applications as an ice-nucleating chemical, a coating in cathode-ray tubes, and as a source of iodine in animal feeds.
