The reaction of various N-tosylated α-amino acids with arenes in the presence of sulfuric acid afforded the corresponding diarylated derivatives in moderate yields, which were generated via decarbonylative arylation followed by Friedel-Crafts reaction of the generated tosylamide derivatives.

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.
