Ligand-free Pd/C-catalyzed Suzuki–Miyaura coupling reaction for the synthesis of heterobiaryl derivatives

We have developed a mild and efficient protocol for the ligand-free and heterogeneous Pd/C-catalyzed hetero Suzuki-Miyaura coupling reaction that allows for the synthesis of both heteroaryl-aryl and heteroaryl-heteroaryl derivatives in good to excellent yields.
