  便利地合成二卤代二苯乙炔的双消除方案：量身定制的苯撑乙炔的多功能构建基块

  摘要：

  二卤代二苯基乙炔可通过β-取代的砜的双消除反应方便地合成，所述β-取代的砜容易从卤素取代的苄基砜和苯甲醛衍生物获得。仅通过选择起始化合物的芳环上卤素的取代位置，就可以在二苯乙炔骨架中的任何所需位置掺入卤素。由此获得的具有不同卤素取代基的二苯基乙炔由于卤素的不同反应性而经历了顺序的碳-碳键形成。因此，可以在任何位置的二苯基乙炔骨架上结合各种部分，从而可以设计各种具有调节的结构和组成的量身定制的亚苯基-亚乙炔基。

• 1,2-Diarylethenyl Sulfones: Readily-Prepared Masked Diarylethynes for Access to Aryleneethynylenes

  1,2-Di(halophenyl)ethenyl phenyl sulfones were prepared readily by successive treatment of halophenylmethyl sulfones with LiHMDS (lithium hexamethyldisilazide), halobenzaldehydes, diethyl chlorophosphate and LiHMDS. The di(halophenyl)ethenyl sulfones thus obtained were transformed successfully to aryleneethynylenes by Sonogashira coupling with arylethyne followed by LiHMDS-promoted elimination of phenylsulfinic acid.

  通过用六甲基二硅氮化锂（LiHMDS）、卤代苯甲醛、氯磷酸二乙酯和六甲基二硅氮化锂连续处理卤代苯甲基砜，可以很容易地制备出 1,2-二（卤苯基）乙烯基苯砜。这样得到的二（卤苯基）乙烯基砜通过与芳基乙炔的 Sonogashira 偶联，然后在 LiHMDS 的促进下消除苯亚磺酸，成功地转化为芳基乙炔。

  A double elimination protocol has been established for access to unsymmetrically substituted aromatic polyynes by use of dialdehyde and substituted benzylic or propargylic sulfones as starting compounds. For this protocol, various substituted sulfones and phthalaldehydes were usable giving rise to the formation of the desired substituted aromatic polyynes. (C) 2003 Elsevier Ltd. All rights reserved.
