Beschreibung

Anwendung

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
nonactivated aryl iodides in hexamethylphosphoric triamide to form aryl sulfides.[2]
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.[3]
• Reaction between acetylenes and metal halides in diethylamine to form transition metal alkynyl complexes.[4]
• Reaction between terminal alkynes with phenylchalcogenyl halides to form alkynyl selenides, sulfides and tellurides.[5]
