Synthesis and Biological Evaluation of Biphenyl Derivatives of Hydrazine via Palladium Catalyzed Suzuki-Miyaura Coupling Reaction

Generally, several methods for the construction of biphenyls, including Stille coupling, GombergBachmann reaction, Ullmann reaction and Suzuki-Miyaura cross-coupling are reported. In present research, considering the particularities of these methods and the characteristics of the target compounds by Suzuki-Miyaura cross-coupling reaction. To investigate the optimal conditions, a model reaction was performed using 1-bromo-4-iodobenzene and phenyl boronic acid under different conditions. The products were characterized by FT-IR, mass, 1H NMR and 13C NMR spectroscopy.
