  • 'Palladacycle' catalyst, developed by W. A. Herrmann et al, which has been reported to surpass all previously known catalysts in the Heck coupling of aryl halides with olefins, with turnover numbers of up to 200,000: Angew. Chem. Int. Ed., 34, 1844 (1995); DE 4,421,730 (1995 to Hoechst A.-G.); Tetrahedron Lett., 37, 6535 (1996).
