A Highly Active Catalyst for Suzuki–Miyaura Cross‐Coupling Reactions of Heteroaryl Compounds

Unprecedented activity: Catalysts derived from Pd and bulky dialkylphosphinobiaryl ligands are shown to be highly stable and active in Suzuki–Miyaura reactions of heteroaryl halides and heteroaryl boronic acids/esters (e. g. , 3- or 4-pyridine, indole, and N-protected pyrrole derivatives). Furthermore, this catalyst system is not inhibited by the presence of highly basic aminopyridines or aminopyrimidines.
