A new method for the preparation of substituted 9,10-diarylanthracenes is described. These compounds are ring closed under palladium catalysis yielding the novel asymmetrically substituted rubicenes and heterocyclic rubicene analogoues.

towards disubstituted rubicenes was devised [2]. A metal catalyzedring closure was found to afford heterocyclic analogues of rubicene and asymmetrically disubstitutedderivatives [3]. In this paper we wish to report some more applications of rubicene in systems havinggreat potential as supramolecular building blocks, namely macrocycles and crown ethers. Macrocyclescontaining a rubicene moiety could be interesting
