The four isomeric diÑuoro-2,11-dithia [ 3.3 ] paracyclophanes, with one Ñuorine 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,arº-diÑuoro [ 2.2 ] paracyclophanes, as a mixture of pseudogemin
## Abstract The signs of all ^13^C^19^F and ^1^H–^19^F coupling constants in fluorobenzene, some substituted derivatives, and in 2‐fluoropyridine have been related using single‐frequency ^13^C{^1^H} double resonance techniques. All ^13^C^19^F couplings in these compounds are shown to be positive
