metal(II) complexes [M(II)(L)(Phen)], [M(II)(L)(Pip)] (M = Ni, Cu, and Zn) (H2L = 2,2′-methylenebis(4-nitrophenol)) (Phen =1,10-phenanthroline) (Pip = Piperazine) has been synthesized by incorporating the metal ion with bisphenol and 1,10-phenanthroline/piperazine ligands. The prepared metal complexes were characterized by FT-IR, UV–vis, 1H NMR, EPR, and mass spectrometry. The metal(II) complexes were
摘要 一系列新的空气稳定过渡金属 (II) 配合物 [M(II)(L)(Phen)], [M(II)(L)(Pip)] (M = Ni, Cu, and Zn) (H2L = 2,2'-亚甲基双(4-硝基苯酚)) (Phen =1,10-菲咯啉) (Pip = 哌嗪) 已通过将金属离子与双酚和 1,10-菲咯啉/哌嗪配体结合而合成。通过FT-IR、UV-vis、1H NMR、EPR和质谱对制备的金属配合物进行表征。在优化条件下,金属 (II) 配合物是各种芳基卤化物的 Suzuki-Miyaura 和 Kumada-Corriu 偶联的有效催化剂。图形概要
