Four novel N,N-bidentate triarylmethane-based ligands I [Ar = Ph, 4-methylphenyl, 3-nitrophenyl] bearing β-pyridyl residues have been prepared and the catalytic activity of their in-situ generated palladium complexes were studied in the Suzuki-Miyaura cross-coupling reactions. Air and moisture stable 3,3′-((arylmethylene)bis(4-methoxy3,1-phenylene))dipyridines I showed excellent activity in the Suzuki coupling reactions of aryl halides with aryl boronic acids under thermal and sonochem. reaction conditions. The described methodol. provided good to high yields in short reaction times at ambient conditions. Moreover, it offered a straightforward way for Suzuki-Miyaura chemo- and homoselective cross-coupling of aryl halides with Ph boronic acid. The structures of synthesized compounds were fully characterized by FT-IR, 1H-NMR, 13C-NMR, and elemental analyses. The coordination of palladium acetate to nitrogen sites of I [Ar = Ph] was also studied using FTIR spectroscopy, EDX anal. and SEM observations. The in-situ generated Pd-complexes of N,N-bidentate ligands I were described as robust and highly effective catalytic systems for the Suzuki cross-coupling of aryl halides with aryl boronic acids under thermal and sonochem. reaction conditions. In addition to this study using Pyridin-3-ylboronic acid, there are many other studies that have used Pyridin-3-ylboronic acid(cas: 1692-25-7Product Details of 1692-25-7) was used in this study.
Pyridin-3-ylboronic acid(cas: 1692-25-7) belongs to pyridine. In industry and in the lab, pyridine is used as a reaction solvent, particularly when its basicity is useful, and as a starting material for synthesizing some herbicides, fungicides, and antiseptics.Product Details of 1692-25-7
