Nickel-catalysed Suzuki–Miyaura cross-coupling reactions of aryl halides with arylboronic acids in ionic liquids

• Excellent green catalytic system for the nickel-catalysed Suzuki reaction
• Efficient yield for aryl halides with arylboronic acids in ionic liquids
• Large amount of synthesis using a simple and economical process

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 catalytic system.
