An exceptionally facile "contrathermodynamic" multipositional isomerization of alkynes
with potassium 3-aminopropylamide.
The reactions' gluing powers have also proven extremely effective at binding fluorescent alkyne
dyes to proteins and other biological components, which allows researchers to observe how they behave in cells and what roles they may play in diseases.
Caption: Molecules with a diazonium group on one end and an alkyne
group on another can serve as a 'primer' to build up ultra-thin layers of electronically active molecules.
However, the transition state corresponding to the deprotonation of alkyne
in this complex was not found.
An alternative to using an alkyne
is to use norbornadiene which can be thought of as a masked alkyne
These polymers have gained a huge interest academically in recent years as the azide group can undergo a cycloaddition reaction with a terminal alkyne
group in presence of a Cu(I) catalyst to make block, graft, brush, and star polymers.
The contributions describe approaches for conjugating proteins and peptides to polymers, generating complex macromolecular architectures via orthogonal and selective cycloadditions, fabricating alkyne
and azide functionalized surfaces, and designing multifunctional network polymers.

1] in the spectra of the PHF also demonstrated that the peanut hull contained large amounts of lingo-cellulosic material, as lignin was a complex amorphous polymer which was constructed by alkynes
group, carbon-carbon bonds and ether link.
react with ethylene to enhance carbon nanotube synthesis, suggesting a polymerization-like formation mechanism.
Most methods employ a stoichiometric amount of organometallic reagents (such as organolithium or organomagnesium) for forming alkynylmetal reagent from alkynes
or alkynyl halides in anhydrous organic solvent.
