Tantal(izing) catalysis : Mesoporous tantalum oxides were treated with 1.0 M sulfuric acid and evaluated for their catalytic activity and selectivity to 2‐phenyl isomers in the alkylation of benzene with bulky olefins (see scheme). The sulfated mesoporous Ta oxide showed comparable activity to H‐Y zeolite, but much higher 2‐phenyldodecane selectivity in mild reaction conditions. The high activity and selectivity was rationalized by the eased diffusion of bulky reactants in the mesoporous frames.
