Azo-amide palladium(II) complexes: Synthesis, characterization and application in C–C cross-coupling reactions

Highly Efficient Method for Suzuki Reactions in Aqueous Media

“…It has also been demonstrated that the use of palladium phosphine species ,, is an excellent strategy for Suzuki couplings under very low palladium loadings. However, phosphine ligands are expensive, toxic, and usually hydrophobic and air-sensitive; therefore, cross-coupling reactions under phosphine-free conditions are still an important challenge for researchers. − Recently, different phosphine-free ligands as diverse as N-heterocyclic carbenes, diimines, diamines, and amides have attracted considerable attention as competent ligands for Suzuki reactions.…”

Benzotriazole derivatives palladium complex: Synthesis, characterization, antifungal and catalytic activity

“…This results show that both catalyst are regioselective towards Estilbene, keeping a selectivity in 80-85% during the reaction. After 1 h of reaction, was observed a higher conversion of yodobenzene in the reaction catalyzed by 7, 84.62%, versus 60.98% converted by 8, this values are in the average for similar compounds [8], in turn, the percentage of selectivity of each species produced is also affected by the difference in the ligands of each catalyst. The catalytic precursor of type 7 offers a selectivity towards E-stilbene of 85.03% and of 14.97% towards 1,1-diphenylethene, while complex 8 is selective in 53.51% and 36.49% towards E-stilbene and 1,1diphenylethene, respectively.…”

“…In vitro antifungal activities of synthesized ligands (3,5) and complexes (7,8) were carried out using the broth microdilution method, recommended by the CLSI, and the diffusion method in potato and dextrose agar (PDA) was used to verify the presence of the fungus A. niger and compared with standard antifungal drug Ketoconazole at the same concentration.…”

Palladium complexes derived from benzoylthiourea ligands: Synthesis, crystal structure, and catalytic application in Suzuki C–C coupling reactions

“…[1][2][3][4][5] Palladium-catalyzed Suzuki C-C coupling reactions of arylhalides with arylboronic acids have been considered as one of the most valuable synthetic methods for the preparation of symmetric and nonsymmetric biaryl compounds that are widely used in numerous natural products, polymers, agrochemicals, pharmaceuticals, materials, and synthetic chemistry. [6][7][8][9][10][11][12][13][14][15][16] In addition, palladium complexes that can be varied with many ligands, such as phosphines, [17][18][19][20] imidazole, [21] pyridine, [22] dibenzylideneacetone, [23] porphyrins, [24] phthalocyanines, [25] and thiols, [26] were successfully carried out as catalyst for this coupling reaction. As compared with benzoylthiourea ligands, some of the ligands are relatively more expensive, less thermally and chemically stable.…”
