A mild method for stereo- and regioselective 1,4-dialkoxylation of conjugated dienes was developed.The reaction is catalysed by palladium(II), and p-benzoquinone is used as the oxidant.It was found that the reaction rate depended on the presence of catalytic amounts of a strong acid.The role of the acid is probably 2-fold: (i) to create a cationic (?-allyl)palladium intermediate and (ii) to protonate the oxygen in the coordinated benzoquinone in the (?-allyl)palladium(benzoquinone) intermediate.
