An efficient strategy for the nickel-catalysed synthesis of biaryls and terphenyls has been developed in environmentally-friendly reaction media. In the presence of β-diketone and PPh3 ligands, Ni(TFA)2 acted as an effective catalyst for the Suzuki–Miyaura cross-coupling of aryl halides and arylboronic acids in an ionic liquid solution. Biaryls and terphenyls were obtained in good yields under this
在环境友好的反应介质中,已经开发了镍催化的联芳基和三联苯合成的有效策略。在存在β-二酮和PPh 3配体的情况下,Ni(TFA)2充当离子液体溶液中芳基卤化物和芳基硼酸的Suzuki-Miyaura交叉偶联的有效催化剂。在该催化体系下,以高收率获得了联芳基和三联苯。
