Beschreibung

Anwendung

Copper(I) iodide, in combination with cesium fluoride, can be used to promote Stille coupling reaction. It can also mediate the reaction between arenethiolate ions and different
nonactivated 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.
