  Preparation of 1,4-bis(2-ethynyl-3-thienyl)benzenes as versatile spacers for connection of heterocycles

  摘要：

  Iodination of 1,4-di(3-thienyl)benzene gave 1,4-bis(2-iodo-3-thienyl)benzene, which was converted to 1,4-bis(2-ethynyl-3-thienyl)benzene. Novel 1,4-bis[2-(pyridylethynyl)-3-thienyl]benzene ligands containing the bis(ethynylthienyl)benzene spacer were prepared by Sonogashira reaction. Advantage of the spacer was demonstrated by introducing functionalized alkyl groups to the 5-position of the thiciphene ring of 1,4-bisl2-(trialkylsilylethynyl)-3-thienyl]benzene.

  4,4'-Bis[2-(2-phenylethynyl)-3-thienyl]biphenyl, 4,4'-bis[2-[2-(trimethylsilyl)ethynyl}-3-thienyl]biphenyl and their congeners were prepared and their properties were studied. Extension of pi-system through the central benzene ring was suggested by UV-vis spectra. Connection of two 1,4-bis[2-2-(trimethylsilyl)ethynyl}-3-thienyl]benzene units was exemplified.
