Abstract
Iron pillared clays (Fe-PILC) were compared to Fe-exchanged K10 (Fe-K1 0) for the oxidative coupling of 2-naphthols to the corresponding bina phthols. Fe-K10 appeared as the most efficient heterogeneous catalyst giving nearly quantitative yields with many naphthols. The highest act ivity displayed by Fe-K10 is attributed to the easier accessibility of catalytic sites of the clay. The catalyst can be recycled several tim es with success.
