摘要：
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 allcynyl chalcogenides in moderate to excellent yields in the presence of K3PO4 as the base under aerobic conditions. (C) 2014 Elsevier Ltd. All rights reserved.
