A highly efficient Schiff-base derived palladium catalyst for the Suzuki–Miyaura reactions of aryl chlorides

A new palladium complex derived from a bidentate Schiff-base ligand showed excellent activity as catalyst for the Suzuki–Miyaura cross-coupling reactions of less reactive aryl chlorides with arylboronic acids. Under an optimized condition, moderate-to-excellent yields of biaryls were obtained with a wide range of substrates at a relatively low loading of catalyst (0.2 mol %).
