The four isomeric diΓ‘uoro-2,11-dithia [ 3.3 ] paracyclophanes, with one Γ‘uorine substituent per aromatic ring 3F 2 , were prepared as a 1 :1 :1 :1 mixture. They were converted into the bissulphones, which were pyrolysed to yield the ar,arΒΊ-diΓ‘uoro [ 2.2 ] paracyclophanes, as a mixture of pseudogemin
