Zinc bromide promoted allylation of aluminum acetals derived from perfluoro carboxylic acid esters and diisobutylaluminum hydride. New convenient access to α-perfluoroalkylated homoallyl alcohols

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.
