Usage Examples English
  • It is used for hydroboration–oxidation reactions of terminal alkynes, giving aldehydes via anti-Markovnikov hydration followed by tautomerization.
  • Terminal alkynes yield the corresponding acid or ester, internal alkynes yield diketones, and alkenes give epoxides.
  • Reactions between Cu+ and alkynes occur only if a terminal hydrogen is present (as it is slightly acidic in nature). Thus, this reaction is used for identification of terminal alkynes.
  • Substrates for hydrozirconation are alkenes and alkynes.
  • Unlike CuAAC in which only terminal alkynes reacted, in RuAAC both terminal and internal alkynes can participate in the reaction.

  • Various aromatic alkynes can be employed to yield desired disubstituted products with satisfactory yields. Aliphatic alkynes are generally less reactive.
  • Under ultraviolet light diphosphorus tetrafluoride reacts with alkynes connected to trifluoromethyl groups to add difluorophosphino (-PF2) groups on each side of a double bond.
  • The first series of phosphirenium ions were synthesized by reacting alkynes with methyl- or phenylphosphonous dichloride and aluminum trichloride.
  • Terminal alkynes add across α,β-unsaturated ketones in the presence of palladium catalysts.
  • Alkynes, under metal catalysts, for example cobalt, can also go under cycloaddition reaction called alkyne trimerization.

  • Alkynes or ketenophiles can be synthesized by various methods.
  • Aryl alkynes are typically made utilizing the Sonogashira reaction which is the palladium catalyzed cross-coupling reaction of terminal alkynes and aryl halides.
  • Alkynes form complexes with transition metals. Such complexes occur also in metal catalyzed reactions of alkynes such as alkyne trimerization.
  • Alkynes can also serve as dipolarophiles in this reaction.
  • Diphenyl disulfide reacts with alkynes to a 1,2-bis(phenylthio)ethylene. Reported alkynes are ynamides. A photoredox thiol-yne reaction has been reported.
