Sonogashira reaction of aryl halides with terminal alkynes catalyzed by cobalt hollow nanospheres

Sonogashira reaction catalyzed by cobalt hollow nanospheres has been developed. Coupling of alkynes with aryl iodide or aryl bromide in the presence of potassium carbonate, triphenylphosphine, and cuprous iodide provides the corresponding products with moderate to good yields, which reveals obvious...

Summary:Sonogashira reaction catalyzed by cobalt hollow nanospheres has been developed. Coupling of alkynes with aryl iodide or aryl bromide in the presence of potassium carbonate, triphenylphosphine, and cuprous iodide provides the corresponding products with moderate to good yields, which reveals obvious advantages such as low-cost catalyst, the recyclability of the catalyst, and simple experimental operation.
