Bis(thiazole) pincer palladium complexes showed efficient catalytic activity for the Suzuki-Miyaura coupling of aryl halides, allowing the synthesis of biaryls with very high turnover numbers and turnover frequencies. The complexes were successfully applied in the scalable and green synthesis of the key intermediates of bioactive LUF5771 and its analogues.

Three triazine-based conjugated porous polymers (CPPs) are synthesized via a Pd-catalyzed Suzuki-Miyaura coupling reaction between derivatives of 2,4,6-tri(thiophen-2-yl)-1,3,5-triazine (TTT) and 2,4,6-triphenyl-1,3,5-triazine (TPT). Photocatalysis experiments demonstrate that the hydrogen evolution rate (HER) of ThTh-CPP (homopolymer of TTT) reach an exceptional 46.4 mmol g⁻¹ h⁻¹ without co-catalysts, surpassing ThPh-CPP (8.

The development of chiral BODIPYs attracts remarkable interest due to their unique properties, structural diversity, and good photochemical stability, whereas achieving the construction of chiral BODIPYs maintains scarce. Herein, we present an enantioselective synthesis of axially chiral BODIPYs through Suzuki-Miyaura coupling. The newly synthesized chiral BODIPYs and the coassembly showed desirable photophysical properties, including high fluorescence quantum yields and intense CPL, both in solution and the solid state.

Suzuki-Miyaura coupling (SMC), a crucial C-C cross-coupling reaction, is still associated with challenges such as high synthetic costs, intricate work-ups, and contamination with homogeneous metal catalysts. Research intensely focuses on strategies to convert homogeneous soluble metal catalysts into insoluble powder solids, promoting heterogeneous catalysis for easy recovery and reuse as well as for exploring greener reaction protocols. Metal-Organic Frameworks (MOFs), recognized for their high surface area, porosity, and presence of transition metals, are increasingly studied for developing heterogeneous SMC.
