units. The chemistry of 2 towards Bronsted and Lewis acids could, therefore, be investigated quite comprehensively. It was discovered that the reactivity of 2, whose carbon framework resembles the beltregion of the C84 (D2) fullerene, is rather unusual as compared with acyclic model compounds. Whereas the latter could easily be dehydrated to the corresponding planar arenes, the former gave rise to

23, which differs from the fully unsaturated belt by two water molecules. Semiempirical AM1 calculations of the electronic and thermodynamic properties of cyclic fluoranthenes revealed strain energy as the essential reason for the incomplete aromatization of 19. The structures of the macrocycles 19 and 23, one of the monomer precursors, and two diastereomeric epoxybenzo[k]fluoranthenes were elucidated
The reactivity of the double-stranded hydrocarbon cycle with two ether bridges (1) toward iodotrimethylsilane (TMSI) was investigated in some detail. The carbonskeleton of cycle 1 resembles the beltregion of a C84fullerene which makes it a potential precursor to the long sought after fully aromatic derivative. Upon exposure to TMSI, cycle 1 undergoes a cascade of reactions which involve different
