The palladium-catalysed arylation of alkenes with aryl bromides or iodides is shown to proceed in high yields at very low palladium concentration when carried out in a suitable strongly polar solvent with a carboxylate anion as base. The preferred combination is N, N-dimethylformamide with sodium acetate. The reaction is markedly dependent on the substituents in the aryl bromide, being favoured by
