The treatment of allylic p-tolyl sulfones with a catalytic amount of [Pd(PPh3)4] gave the 1,3-rearrangement products in high yields. A convenient method for the preparation of α,β-unsaturated ketones using [Pd(PPh3)4] as a catalyst from the 1,3-rearrangement products, 2-tosylhomoallyl alcohols, is also described.
