NCN pincer ligands based on 1,2,4-triazole and their corresponding palladium(II) complexes have been synthesized by the reaction of 1,3-bis(1H-1,2,4-triazol-1-ylmethyl)benzene derivatives with palladium(II) acetate. All compounds are ortho,ortho-metalated. Chiral complexes were obtained by using pincer ligands with substituents on the arms. The chiral complexes are conformationally rigid up to 150
通过1,2-双(1 H -1,2,4-三唑-1-基甲基)苯衍生物的反应合成了基于1,2,4-三唑的NCN钳位配体及其相应的钯(II)配合物用乙酸钯(II)。所有化合物均为邻位,邻位金属化。通过使用在臂上具有取代基的钳位配体获得手性络合物。手性络合物在高达150°C的条件下呈构象刚性。
