Direct geminal diallylation of propiophenone with allyl bromide has been achieved in the presence of vanadium(II) species. By applying this method, direct construction of asymmetric quaternary carbons from propiophenone has been accomplished. Strong oxophilicity of the low-valent vanadium facilitated the deoxygenative reaction. The present reaction is characteristic of vanadium complexes.
