Chemistry of bis(2-ethynyl-3-thienyl)arene and related systems. Part 6: preparation of 1,4-bis(2-ethynyl-3-thienyl)benzene derivatives containing fluorine atoms at the 2,3- or 2,5-positions of the benzene ring

摘要

Fluorine-substituted 1,4-bis(2-ethynyl-3-thienyl)benzene derivatives were prepared, utilizing Suzuki-Miyaura and Sonogashira cross coupling reactions. Their UV spectra were compared with some related compounds.
