Abstract The conformational preferences in solution of eight new open-chain and cyclic aromatic sulphides containing pyridine or 1, 3, 4-thiadiazole units have been investigated, parallel to those of some structurally related phenyl sulphides, by means of 1 H NMR spectroscopy. The results obtained have shown that replacement of phenyl by the pyridyl or the 1, 3, 4-thiadiazolyl moieties induces slightly different propeller arrangements, ascribed ...
