  Dialkynylation of aryl aldehydes using dialkynylboron chlorides: A transition-metal-free route to 1,4-diynes

  摘要：

  Dialkynylboron chlorides couple smoothly with aryl aldehydes at room temperature to afford 1,4-dialkynes in good to excellent yields. Dialkynylboron halides act simultaneously as Lewis acid and reactant in this coupling reaction. (C) 2012 Elsevier B. V. All rights reserved.

  A titanocene-catalyzed multicomponent coupling is described herein. Using catalytic titanocene, phosphine, and zinc dust, zinc acetylides can be generated from the corresponding iodoalkynes to affect sequential nucleophilic additions to aromatic aldehydes. The intermediate propargylic alkoxides are trapped in situ with acetic anhydride, which are susceptible to a second nucleophilic displacement upon

  本文描述了钛茂催化的多组分偶联。使用催化的钛茂，膦和锌粉，可以从相应的碘代炔烃生成乙炔锌，从而影响向芳香族醛的连续亲核加成。中间体炔丙基醇盐被原位捕获用乙酸酐，乙酸酐在用各种富含电子的物质处理后易发生第二次亲核取代，这些富含电子的物质包括乙炔化物，烯丙基硅烷，富电子芳族化合物，甲硅烷基烯醇醚和甲硅烷基烯酮缩醛。另外，使用环丙烷甲醛导致碘掺入导致开环产物。综上所述，这些结果构成了三组分偶联反应新模式的基础，该模式允许在单个合成操作中快速获得增值产品。

  The coupling of alcohols with alkenyl- and alkynylboron dihalides with high olefin stereoselectivity is described. The reaction provides a facile route to internal acetylenes. Notably, the allylation of propargylic alcohols mediated by boron trichloride proceeds smoothly at room temperature and gives excellent regioselectivity.

  directly from aromatic aldehydes is described. The starting aldehyde behaves as a traceless functionality in the formation of multiple carbon–carbon bonds through consecutive carbon–heteroatom bond activations. The sequential addition of a metal acetylide and a second carbon nucleophile to the dielectrophilic aldehyde enables the construction of symmetrical and unsymmetrical 1,4-diynes in good yields
