Schiff Base-Pd(II) Complexes Containing Pyridine and Thiophene Rings: Synthesis, Characterization, Suzuki-Miyaura C-C Coupling Reactions

Abstract

S chiff bases are a multinucleated ligand group that forms complexes with many metal atoms through donor atoms. They have been extensively studied due to their important properties such as easy accessibility, low cost, selectivity and sensitivity to central metal ions [1][2][3][4][5][6]. Schiff base complexes exhibit high catalytic activities for a wide range of chemical reactions (e.g., hydrosilylation, homogenous catalyst, transfer hydrogenation, C-C coupling reactions and epoxidation) [7][8][9]. The Suzuki-Miyaura reaction, which is one of the present C-C cross-coupling reactions, is the most important reaction between aryl halides and arylboronic acids and widely used to obtain biaryls. The Suzuki-Miyaura coupling reaction has been extensively studied in the field of synthesis owing to its ease of operation, perfect functional group compatibility, attainable and environmental friendly properties of the initial reagents. Due to their superior properties, biaryls is a widely preferred compound in numerous industrial applications such as pharmaceuticals, natural products, agrochemicals, advanced materials, cosmetics [10][11][12][13][14][15][16][17].
