   In cross-coupling (especially Pd-catalyzed C–N/C–C bond formation), researchers often set multiple goals at once: more challenging substrates (Ar–Cl/heteroaryl chlorides), less metal (low Pd loading), larger scale (scale-up), and tighter control of outcomes (stable impurity profile and ...

   C(sp2)- and C(sp)-hybridized coupling reactions are established catalytic approaches. However, multi-step C(sp3)- and C(sp2)-coupling reactions of boronic acids and related derivatives are still limited by ineffective two-electron transmetalation reactions. These conventional protocols exhibit ...
