Synthesis of biaryls and polyaryls by ligand-free Suzuki reaction in aqueous phase

A highly efficient palladium acetate-catalyzed ligand-free Suzuki reaction in aqueous phase was developed in short reaction times (0.5-1 h) at 35 °C in air. The key for such a successful catalytic system was the use of a suitable amount of cosolvents in the aqueous phase. The method could be extended to the consecutive multi-Suzuki coupling, and polyaryls were prepared in a single one-pot step in high selectivity and excellent yield under mild reaction conditions (60 °C).

Simple and efficient phosphine-free Pd(OAc)2 catalyzed urea accelerated Suzuki-Miyaura cross-coupling reactions in iPrOH-H2O at room temperature

A simple, efficient, and less expensive protocol for the phosphine-free Suzuki-Miyaura cross-coupling reactions of aryl halides with different aryl boronic acids in iPrOH-H2O under aerobic conditions has been developed. The mixture of Pd(OAc)2 and urea catalyzes the Suzuki-Miyaura cross-coupling of a variety of aryl halides with aryl boronic acids at room temperature, giving generally high yields even under low catalytic loads. The effect of solvent, base, and catalyst loading on the coupling reaction of aryl halide with arylboronic acid is also described.

Suzuki coupling catalyzed by a homoleptic Pd(I)-Pd(I) solvento complex

The PdI-PdI bonded complex [Pd2(CH3CN)6][SbF6] 2 is catalytically active towards Suzuki cross-coupling reactions of aryl bromides or chlorides with various arylboronic acids under mild conditions giving good to excellent yields. Its performance is enhanced by the introduction of stoichiometric or limited phosphines. The effects of different ligands, metal oxidation states [Pd(II), Pd(I) Pd(0)], bases and solvents have been examined.

'Awaken' aryl sulfonyl fluoride: a new partner in the Suzuki-Miyaura coupling reaction

An example of the activation of the -SO2F group, which is traditionally considered a stable group even in the presence of a transition metal, is described using a novel partner in the Suzuki-Miyaura coupling reaction catalyzed by Pd(OAc)2 and Ruphos as ligands. The products showed good to outstanding yields and broad functional group compatibility under optimal conditions. The sequential synthesis of non-symmetric terphenyls and the gram grade process highlight the approach's synthetic utility. DFT calculations have shown that Pd0 prefers to insert between C-S bonds rather than S-F bonds. This journal is

Magnetic nanoparticles supported N-heterocyclic palladium complex: Synthesis and catalytic evaluations in Suzuki cross-coupling reaction

Because of the robustness and magnetic properties, the magnetic materials are promising and alternative candidate for the fabrication of noble metal in chemical catalysis from the viewpoint of green chemistry. Accordingly, an eco-friendly magnetic palladium catalyst loaded on N-Methylimidazole functionalized Fe3O4@SiO2 nanoparticles (Fe3O4@SiO2-NMIM-Pd) has been designed and prepared in the present work. The resultant composite exhibited excellent catalytic activity towards the Suzuki cross-coupling reaction for the synthesis of the corresponding biaryls in good to excellent yields (up to 96%) under aerobic conditions. In particular, this catalyst could be easily recovered through magnetic separation in a few cycles. The as-prepared palladium complex showed advantages including high thermal stability, low toxicity, moisture and oxygen insensitivities in Suzuki reactions. More importantly, this study presents a catalysis system, which will provide the magnetic materials access to the potential applications in a wide range of green organic catalysis.
