Conjugated diynes have attracted more and more attention not only for their unique rod like structures and wide existence in nature product, but also the abundant properties and derivations of them. Although oxidative dimerization of alkynes or Cadiot–Chodkiewicz reactions were the main pathway and have achieved great success in the synthesis of diynes, oxidative cross coupling, FBW rearrangement as well as diyne metathesis emerged rapidly recently. Moreover, diynes could be precursors of basic heterocycles, which represented an emerging research area. This Letter will cover the recent progresses in the synthesis and further derivations of diynes.

1,3-二炔化学：合成与衍生

共轭二炔不仅因其独特的杆状结构和在自然产物中的广泛存在而吸引了越来越多的关注，而且它们的丰富性质和衍生物也得到了越来越多的关注。尽管炔烃的氧化二聚化或Cadiot-Chodkiewicz反应是主要途径，并且在二炔的合成中取得了巨大成功，但氧化交叉偶联，FBW重排以及二炔复分解反应近来迅速出现。此外，二炔可能是基本杂环的前体，这代表了一个新兴的研究领域。这封信将涵盖二炔的合成和进一步衍生的最新进展。
