Ligand-free Pd(OAc)2 catalyzed Heck reaction under air was studied in this work. Iodobenzene, bromobenzene and their derivatives reacted smoothly with different alkenes in the presence of palladium acetate. The reactions were conducted under air in the absence of ligand. The effect of base, additives, solvents and catalysts on this transformation was investigated. The optimized reaction conditions were approved as: Pd(OAc)2 (5 mol%), Ag2CO3 (0.6 equiv.), reflux in benzene or toluene under air.
