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.
2,2'-联吡啶配体（dsbpys）具有哑铃状形状，在 C5 和 C5'位置具有不同取代的三芳基甲基基团，在 Ni 催化的交叉电子亲核偶联反应和 Ni/光氧化还原协同催化脱羧偶联反应中表现出优异的配体性能。dsbpys 与传统 bpy 配体相比具有优越的配体效应，这归因于 dsbpys 的单螯合性质。
