Özet
In the present study, synthesis and catalytic properties of palladium PEPPSI type complexes of cycloheptyl substituted N-heterocyclic carbene ligand were reported. Different N-coordinate ligands including pyridine, imidazole and thiazole derivatives were used to stabilize the complexes. Structures of complexes were established by H-1 NMR, C-13 NMR, IR spectroscopic methods and elemental analyses. All complexes were applied to Suzuki-Miyaura cross coupling reaction in aqueous media. After the optimization of reaction conditions, all complexes were tested on the cross coupling of five different aryl chloride derivatives and phenylboronic acid. Pyridine containing complex, 3a performed stronger catalytic performance than others. (C) 2019 Elsevier B.V. All rights reserved.
