Ligand-Free Heck Reaction: Pd(OAc)2 as an Active Catalyst Revisited

Abstract
Palladium acetate was shown to be an extremely active catalyst for the Heck reaction of aryl bromides. Both the base and the solvent were found to have a fundamental influence on the efficiency of the reaction, with K3PO4 and N,N-dimethylacetamide being the optimal base and solvent, respectively.
