Synthesis and inclusion properties of a novel macrocyclic hexaketone monohydrate with a hemiacetal structure

A macrocyclic hexaketone monohydrate was synthesized by the oxidation of either tribenzohexadehydro[12] annulene or tribenzotetradehydro[12] annulene-1,2-dione with ruthenium catalysts; the hexaketone monohydrate incorporates small molecules with a hydroxy, carbonyl or ether group in the crystalline lattice to form inclusion complexes.
