A new indolylphosphine WK‐phos has been synthesized for Pd‐catalyzed Suzuki–Miyauracoupling of (hetero)aryl chlorides with (alkyl)arylboronicacids. The catalyst system with this new ligand was found to be highly effective in facilitating the reaction even at catalyst loading levels in the parts per million range (e.g. 10 ppm).

Pd–PEPPSI complexes were designed and synthesized. The relationship between catalyst structure and properties was systematically investigated. It was revealed that “bulky‐yet‐flexible” C3 bearing ancenaphthyl backbone was a highlyefficient precatalyst and could be successfully employed in Suzuki–Miyaura reactions of (hetero)arylchlorides with (hetero)arylboronic acids at a low palladium loading in the presence
