Recently, many efforts have been directed towards palladium catalysts with superior profiles to the often thermally unstable Pd(0) catalysts usually prepared in situ. During this research, Hermann and Beller developed palladacycle 1 as a thermally stable and versatile catalyst. 1 was shown to give significantly higher turn over numbers (TON) than many in situ prepared systems in Heck-type reactions, and it was also used successfully for palladium-catalyzed Suzuki, Stille, Negishi, Songashira coupling reactions as well as for aromatic aminations.
