    Synthesis of Diynes and Tetraynes from in Situ Desilylation/Dimerization of Acetylenes
    摘要:
    [GRAPHICS]An efficient method for the in situ desillylation/oxidative dimerization of (trialkylsilyl)acetylenes is described. This protocol avoids the complications encountered with sensitive diynes by eliminating the deprotection and isolation steps. Various aromatic and alkyl diynes and tetraynes can be synthesized in a straightforward manner in good yields (82-99%) from TIPS-protected acetylenes. This method facilitates the efficient synthesis of novel tetrayne-bridged acetylenic cyclophanes 6 and 7 in a direct manner.

  • Exploiting the dual role of ethynylbenziodoxolones in gold-catalyzed C(sp)–C(sp) cross-coupling reactions
    作者:Somsuvra Banerjee、Nitin T. Patil
    DOI:10.1039/c7cc04283c
    日期:——
    Reported herein is the gold-catalyzed alkynylation of terminal alkynes using ethynylbenziodoxolones (EBXs), where EBXs serve a dual role as oxidants as well as alkyne transfer agents to access unsymmetrical 1,3-diynes. Hence, the catalytic system requires no external oxidants and is compatible with a broad range of substrates, including those with polar functional groups such as NH, OH and B(OH)2.
    本文报道的是使用乙炔基苯并恶恶唑酮(EBX)的末端炔烃催化炔基化反应,其中EBX担当氧化剂和炔烃转移剂的双重角色,以访问不对称的1,3-二炔。因此,该催化体系不需要外部氧化剂,并且与各种底物兼容,包括具有极性官能团(例如NH,OH和B(OH)2)的底物。
