A functionalized phosphine ligand with a pentaarylbenzene moiety in palladium-catalyzed Suzuki-Miyaura coupling of aryl chlorides

A functionalized phosphine with a pentaarylbenzene moiety was found to facilitate the palladium-catalyzed Suzuki-Miyaura coupling of aryl chlorides. The new ligand achieved high turnover numbers (up to TON 5000).
