Copper(I) iodide, in combination with cesium fluoride, can be used to promote Stille coupling reaction.[1] It can also mediate the reaction between arenethiolate ions and different non activated aryl iodides in hexamethylphosphoric triamide to form aryl sulfides.
Copper(I) iodide can be used to catalyze:
- Thioetherification of aryl halides using thiourea and alkyl bromides in wet polyethylene glycol and in the presence of potassium carbonate as a base.
- Reaction between acetylenes and metal halides in diethylamine to form transition metal alkynyl complexes.
- Reaction between terminal alkynes with phenylchalcogenyl halides to form alkynyl selenides, sulfides and tellurides.
