Previously we synthesized a series of phosphacyclophanes on the basis of benzene-, biphenyl-, and naphthalenediols [1]. This new type of cavity systems is of particular interest that is associated with the ability of phosphorus to form a wide range of functional groups, as well as by the possibility to make use of the [square] factor characteristic of the starting aromatic systems.Proceeding with these works, we synthesized first representatives of phosphocyclophanes on the basis ÄÄÄÄÄÄÄÄÄÄÄÄ of anthracene-2,6-diol. There are scarce data in the literature on phosphorylation of anthracene and its derivatives [2], which is probably explained by the fact that the starting compounds are hardly available and extremely unstable. We suggested to approach anthracene-2,6-diol via a combination of two known procedures [3] and thus could much improve its yield.To prepare a phosphacyclane comprising anthracene residues, we reacted equimolar amounts of anthracene-2,6-diol and hexaethylphosphorous triamide.
