  Highly stereoselective synthesis of para-substituted (E)-N-styrylcarbazoles via sequential silylative coupling–Hiyama coupling reaction

  摘要：

  A series of new para-substituted (E)-(N)-styrylcarbazoles, i.e., eight (E)-9-[2-(aryl)ethenyl]-9H-carbazoles (5-12) and 1,4-bis[(E)-2-(9H-carbazol-9-yl)vinyl]benzene (13), have been synthesized in high yield and stereoselectively by a sequential silylative coupling-Hiyama coupling reaction, i.e., coupling of commercially available 9-vinylcarbazole with vinyltriethoxysilane or divinyltetrame-thyldisiloxane in the presence of [RuHCl(CO)(PCy3)(2)] (1), followed by Pd (11) catalyzed cross-coupling with para- substituted iodobenzenes. The tandem procedure has facilitated the synthesis of 13. X-ray structures of the intermediate silylvinylcarbazole (4), as well as products 12 and 13 have been obtained. (c) 2006 Elsevier Ltd.
