Abstract

Adamant about this: A variety of aryl and heteroaryl propargyl ethers are obtained in good to excellent yields from activated and non-activated aryl bromides and chlorides in the presence of a sterically hindered, air-stable ligand by using a general palladium-catalyzed synthesis. Our protocol complements the known syntheses for alkynyl aryl ethers and 2H-1-benzopyrans and should find further applications in organic synthesis.
