3,7-Diiodo-2,6-di(thiophen-2-yl)benzo[1,2-b:4,5-b']difurans are efficiently prepared by an iodine-promoted double cyclization. This new heterocyclic core is readily modified by the attachment of alkyl chains for improved solubility. The use of these compounds for the synthesis of new conjugated polymers is also reported.
3,7-二碘-2,6-二(噻吩-2-基)苯并[1,2-b:4,5-b']二呋喃可通过碘促进的双重环化反应有效地制备。通过连接烷基链,很容易对这个新的杂环核心进行修饰以提高其溶解度。还报告了这些化合物在合成新型共轭聚合物中的应用。
