and easily available, stable starting materials were used, resulting in a concise and highly efficient route for the synthesis of the title compounds. This novel pseudo five-component synthesis starting from iodo(hetero)arenes is particularly suitable as a direct access to well-defined thiophene oligomers, which are of peculiar interest in materials science.
基于连续的一锅 Sonogashira-Glaser 偶联环化序列,合成了多种 2,5-二(杂)芳基
噻吩,收率中等至良好。使用单一的 Pd/Cu 催化剂系统,无需进一步添加催化剂,并且使用容易获得、稳定的起始材料,从而为合成标题化合物提供了一条简洁高效的路线。这种从
碘(杂)
芳烃开始的新型伪五组分合成特别适合直接获取定义明确的
噻吩低聚物,这在材料科学中具有特殊意义。
