Popis: Ligand-promoted room-temperature Pd(II)-catalyzed direct C–H alkynylation of phenylacetic amides has been developed using commercially available TIPS-acetylene as an efficient alkynylating reagent, where 8-aminoquinoline was employed as a removable bidentate auxiliary, thus giving rise to optically pure ortho-alkynylated α-APA in a highly efficient manner.
