Application
1-Amino-3-butyne, a bifunctional linker can be used:
- In Buchwald–Hartwig amination reaction of 1,2,3,4-tetrahydroacridine trifluoromethanesulfonate derivative.
- As a reagent to synthesize dialkynylamides from diacids.
- For the post-polymerization modification of poly(2-alkyl/aryl-2-oxazoline)s (PAOx) polymer by amidation of its methyl ester side chains.
- As a crosslinker which can bind with resin as well as nanocrystalline cellulose to facilitate the terminal alkyne group for further functionalizations.
