Be independent: Under basic conditions a furan ring entrapped in an aromatic macrocycle readily recovered the properties characteristic for a free molecule and assimilated a water molecule forming the Achmatowicz rearrangement product with a 3-pyranone subunit built in. Coordination of palladium(II) created a complex stabilizing the second tautomer with two sp3 carbon atoms (oxygen red, water green, palladium purple, and the aryl group blue).
