The reaction of aluminum acetals, generated in situ by the reduction between perfluoro carboxylic acid esters and diisobutylaluminum hydride, with a variety of allylstannanes efficiently proceeds in the presence of zinc bromide at 40°C to afford the corresponding α-perfluoroalkyl-substituted homoallyl alcohols in good yields.
