The four isomeric diรuoro-2,11-dithia [ 3.3 ] paracyclophanes, with one รuorine 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,arยบ-diรuoro [ 2.2 ] paracyclophanes, as a mixture of pseudogemin

The 1H, 13C and 19F NMR spectra of 9, 14-diรuoro-2,11-dithia[3.3]metaparacyclophane, and 3F 2 , its 9-monoรuoro derivative, 3F, and of 8,12-diรuoro[2.2]metaparacyclophane, and its 8-monoรuoro deriv-2F 2 , ative, 2F, were experimentally assigned as fully as possible. Two-dimensional shift correlation
A full 1H and 1C NMR study through the use of one-and two-dimensional techniques (HMQC, HMBC, TOCSY and NOE-di โ erence spectroscopy) was carried out on poly[3-(6-methoxyhexyl)-2,2@-bithiophene]. Inter-ring correlations detected in the HMBC spectra proved to be a valuable tool in the assignment of re
