• Synthesis of 1,3-Diynes via Cadiot–Chodkiewicz Coupling of Volatile, in Situ Generated Bromoalkynes
  作者：Phil C. Knutson、Haleigh E. Fredericks、Eric M. Ferreira

  DOI：10.1021/acs.orglett.8b02975

  日期：2018.11.2

  A convenient Cadiot–Chodkiewicz protocol that facilitates the use of low molecular weight alkyne coupling partners is described. The method entails an in situ elimination from a dibromoolefin precursor and immediate subjection to copper-catalyzed conditions, circumventing the hazards of volatile brominated alkynes. The scope of this method is described, and the internal 1,3-diyne products are preliminarily

  描述了一种方便的 Cadiot–Chodkiewicz 方案，该方案有利于使用低分子量炔烃偶联伙伴。该方法需要从二溴烯烃前体中原位消除并立即置于铜催化条件下，从而避免了挥发性溴化炔烃的危害。描述了该方法的范围，并对钌催化的叠氮化物-炔环加成反应中的内部1,3-二炔产物进行了初步评估。

• Copper-Catalyzed Decarboxylative Coupling of Alkynyl Carboxylates with 1,1-Dibromo-1-alkenes

  日期：2013.5.3

  A copper-catalyzed decarboxylative coupling reaction of potassium alkynyl carboxylates with 1,1-dibromo-1-alkenes was developed for the synthesis of unsymmetrical 1,3-diyne and 1,3,5-triyne derivatives. Diverse aryl, alkenyl, alkynyl, and alkyl substituted 1,1-dibromo-1-alkenes can react smoothly with aryl and alkyl substituted propiolates to produce unsymmetrical 1,3-diynes and 1,3,5-triynes with high selectivity and good functional group compatibility.
