摘要
A series of novel ionic liquid-supported Schiff bases have been prepared from the condensation of aromatic aldehydes with the ionic liquid 1-(2-aminoethyl)-3-methylimidazolium hexafluorophosphate. The as-prepared ionic liquid-supported salicyladehyde Schiff base L3 was further investigated as a ligand for the Pd-catalyzed Suzuki-Miyaura coupling reaction under air in ethanol solution, giving biaryls in good to excellent yields. The PdCl2/ligand L3 catalytic system could be reused at least 5 times without losing its activity.
