Abstract

Abstract: 2, 2'‐Bipyridine ligands (dsbpys) with dumbbell‐like shapes and differently substituted triarylmethyl groups at the C5 and C5' positions showed high ligand performance in the Ni‐catalyzed cross‐electrophile coupling and the Ni/photoredox‐synergistically catalyzed decarboxylative coupling reactions. The superior ligand effects of dsbpys compared to the conventional bpy ligands were attributed to the monochelating nature of dsbpys.
