conditions gave, selectively, an isothiazolo[3,4-d]cyclopenta[1,2,3]dithiazole and new cyclopenta[1,2,3]dithiazole derivatives. Similarly, 2-aminocyclohept-1-enecarbonitrile reacted with SCl2, iBu3N and NCS to give a formally antiaromatic cyclohepta[1,2,3]dithiazole. Some of the compounds obtained showed characteristics useful as new materials, for example, as liquid crystals and near-infrared dyes. (© Wiley-VCH
3-Amino-1H-indene-2-carbonitrile 和 2-amino-3H-indene-1-carbonitrile 与 SCl2、iBu3N 和 NCS 反应得到苯并环戊二烯 [1,2,6] 噻二嗪,而 2-aminocyclopent-1-烯腈在相同条件下生成环戊二烯 [1,2,6] 噻二嗪,其与 S2Cl2、SCl2 和 iBu3N 的混合物在不同条件下反应生成异噻唑并 [3,4-d] 环戊二氮 [1,2] ,3]二噻唑和新的环戊二烯[1,2,3]二噻唑衍生物。类似地,2-aminocyclohept-1-enecarbonitrile 与 SCl2、iBu3N 和 NCS 反应得到形式上的抗芳香环庚 [1,2,3] 二噻唑。获得的一些化合物显示出可用作新材料的特性,例如用作液晶和近红外染料。(© Wiley-VCH Verlag GmbH & Co.
