data are analysed in terms of the preferred conformations adopted in solution. In most cases these data are consistent with the presence, in dioxane, of helical conformers, where both aromatic rings are twisted in the same direction with respect to the C Ar SC Ar molecular reference plane. The (4-ClC 6 H 4 ) 2 SO molecule adopts an orthrogonal conformation where both aryl rings are approximately perpendicular
摘要 报告了 (4-NO 2 C 6 H 4 ) 2 S、(4-MeOC 6 H 4 ) 2 S、(4-MeOC 6 H 4 ) (4'-NO 2 C) 的摩尔克尔常数和电偶极矩6 H 4 )S, (2-MeOC 6 H 4 ) (4'-NO 2 C 6 H 4 )S, 4(MeOC 6 H 4 ) (2'-NO 2 C 6 H 4 )S, (2- MeOC 6 H 4 ) (2'-NO 2 C 6 H 4 )S 和 (4-ClC 6 H 4 ) 2 SO 在 298 K 下作为二恶烷中的溶质。根据溶液中采用的优选构象分析数据。在大多数情况下,这些数据与在二恶烷中存在的螺旋构象异构体一致,其中两个芳环相对于 C Ar SC Ar 分子参考平面在相同方向上扭曲。(4-ClC 6 H 4 ) 2 SO 分子采用正交构象,其中两个芳环近似垂直于C Ar SC Ar 分子参考平面。
