2-Bromo-5-ethynylpyridine Chemical Properties,Usage,Production

  • Uses 2-Bromo-5-ethynylpyridine is used in the synthesis of macrocycle of terpyridine units.
  • Preparation The iodobromopyridine (2-Bromo-5-iodopyridine), the starting material, was coupled with TMS-acetylene under Sonogashira conditions. One-pot deprotection and recrystallization could yield the bromo,ethynyl-functionalized pyridine (2-Bromo-5-ethynylpyridine)[1].
    2-Bromo-5-ethynylpyridine
  • Reactions 2-Bromo-5-ethynylpyridine is a useful organic compound that could be used to synthesize 2-Bromo-5-[(3-iodophenyl)ethynyl]pyridine, 2-bromo-5-({4-[(tert-butyldimethylsilyl)oxy]phenyl}ethynyl)pyridine, and so on.
