摘要

The alkyne moiety is a widely occurring motif of natural products, molecular materials and pharmaceuticals.1 Despite the many methods developed for the formation of arylalkynes and conjugated enynes, the Sonogashira coupling of nucleophilic terminal acetylenes with aryl halides2 has almost completely replaced other classical methods of arylalkyne synthesis.3 However, the formation of the homocoupled by-product from the terminal acetylenes is a ...
