Extraordinary reaction rates and selectivity for the conversion of alkyl aromatic compounds, such as p ‐xylene, in terephthalic acid were observed for a heterogeneous perovskite catalyst of composition (La,Sr) 0.5 (Mn,Co) 0.5 O 2.38 (see picture). The oxygen‐deficient catalyst was prepared by reduction of the oxygen‐stoichiometric parent compound.
