Al in : A new strategy was introduced to modify the electronics and steric hindrance of the Pd II ion in order to change its reactivity towards benzene hydroxylation. In trifluoroacetic acid, free Pd II ions provide dominantly biphenyl, with phenol as minor product. Ligation of bpym to the Pd II ion results in its deactivation with regard to benzene functionalization. The addition of the redox inactive Al III ion to the Pd II (bpym) complex recovers its catalytic activity, and alters the reactivity of Pd II ion from benzene coupling to hydroxylation.
