General description

1-Bromo-2-butyne is a propargyl bromide derivative. It is one of the constitutional isomer of bromo butyne. Its Br-loss threshold photoionization breakdown diagram has been analyzed to derive dissociative photoionization thresholds to C4H5+ production. It participates in the preparation of linagliptin.

Application

1-Bromo-2-butyne was used in the alkylation of L-tryptophan methyl ester. It was used as a source to generate CH3CCCH2 radicals to investigate the reaction kinetics of these radicals with NO and NO2.
It may be used in the synthesis of the following:
  • 4-butynyloxybenzene sulfonyl chloride
  • mono-propargylated diene derivative
  • isopropylbut-2-ynylamine
  • allenylcyclobutanol derivatives
  • allyl-[4-(but-2-ynyloxy)phenyl]sulfane
  • allenylindium
  • alkynyl alcohols
  • axially chiral teranyl compounds
Exploited in the synthesis of axially chiral teranyl compounds.
