Trifluoroacetic acid is a naturally occurring organic solvent and biodegradable by microbial action. It can also be used as a catalyst for various organic transformations, including solvolysis, rearrangements, reductions, oxidations, and trifluoromethylation.
Application
Trifluoroacetic acid can be used as a solvent in the:
- Mass spectrometry for protein identification.
- Microwave-irradiated bromination of isoxazoles and pyrazoles with N-bromosuccinimide to synthesize mono-brominated isoxazoles and pyrazoles.
- Lewis acid-catalyzed 6-endo-digcyclization of 2-(2-arylethynyl)heteroaryl esters to heterocyclic lactones.
- Electrospinning of cellulose acetate to prepare the corresponding nanofibrous membranes.
