Highly Active Palladium Catalysts with Bisacetylacetonate Ligands for Suzuki–Miyaura Cross-coupling Reactions in Mild Conditions

Abstract

In the presence of Pd(OAc)2, three bisacetylacetonate ligands were demonstrated to form a highly efficient catalyst for the Suzuki–Miyaura cross-coupling reactions. The most active bisacetylacetonate ligand with anthracene groups on the backbone showed a wide substrate scope in excellent yields using very low catalyst concentration of 0.01 mol % in ethanol/aqueous media under ambient atmosphere.
