  1,2-Dithiins and precursors, XVII: Synthesis and properties of thieno anellated 1,2-dithiins, structural influence on colour

  摘要：

  Various thieno[3,2-c] anellated (59, 26) and dithieno[3,2-c:2,3-e] anellated I,2-dithiins (32 a-c, 45) were obtained starting from appropriate thiophene precursors. The absorption maxima covered the range from 430 to 467 nm indicating olefinic rather than aromatic character of the anellating thiophene units. Access to the isomeric thieno[2,3-c] anellated series failed due to competing reactions in the final stage, e.g. by the formation of the 12-membered cyclic bis-disulfide 53.

  Thioxo-isoindigoide compounds E are accessible only in special cases, depending on the resonance situation in the heterocyclic unit, whereas the thioxo-indigoide species A are at all unknown. Thus the oxidation of the corresponding leuko-isoindigoide precursors affords either 3 as a representative of E by predominance of thioamide conjugation, or the unusual 12-membered cyclic bis-disulfides 4 and 10, respectively, according to type H by predominance of hetarene stabilization.
