双(邻卤代芳基)二乙炔的一种新的分子内三环化反应,通过双硫醚化,然后与硫属元素反应,生成含杂环-1,2-二硫属配基-杂环稠合三环骨架的π共轭化合物。随后用铜金属脱卤得到一系列基于噻吩和硒吩的杂并苯。
A new intramolecular triple cyclization of bis(o-haloaryl)diacetylenes, via dilithiation followed by reaction with chalcogen elements, produces pi-conjugated compounds containing heterole-1,2-dichalcogenin-heterole fused tricyclic skeletons. The subsequent dechalcogenation with copper metal affords a series of thiophene- and selenophene-based heteroacenes.
