Abstract
A general and efficient method for the cross-coupling reaction of diorgano dichalcogenides with terminal alkynes using copper iodide/cryptand-22 (CuI/C22) has been developed. This protocol gave alkynyl chalcogenides in moderate to excellent yields in the presence of K3PO4 as the base under aerobic conditions.
