Palladium(II) complexes featuring bidentate pyridine–triazole ligands: Synthesis, structures, and catalytic activities for Suzuki–Miyaura coupling reactions
2014
Abstract Preparation of the Pd(II) complexes containing 2-(4-R-1,2,3-triazol-1-yl)pyridine [R = C 6 H 5 ( 1 ), NC 5 H 4 ( 2 ), n -C 6 H 13 ( 3 )] were described. Crystal structures of 1 and 2 revealed a square planar geometry with bidentate ligand coordination to Pd using different N donor of the triazole ring. Catalytic studies indicated that 1 – 3 exhibited moderate to high activity for Suzuki–Miyaura coupling between aryl bromides and phenylboronic acid under mild and aerobic conditions.
