Palladium-catalyzed Displacement of Aryl Halide by Tin Analogue of Reformatsky Reagent

Abstract Reaction of ethyl α-(tributylstannyl)acetate with aryl bromides in the presence of zinc bromide or chloride and a catalytic amount of dichlorobis(tri-o-tolylphosphine)palladium was found to give ethyl arylacetates in good yields except with the aryl bromide having p-acetyl or p-nitro group.
