General description
Triethylamine is a volatile organic compound used in several industrial processes such as oxidation, reduction, elimination, substitution, addition, and dehydrohalogenation reactions.
Application
Triethylamine can be used as:
- A catalyst in the Domino ring-opening/recyclization reactions of 1,3-thiazolidinedione, malononitrile, and aromatic aldehydes to synthesize polysubstituted dihydrothiophenes.
- A base to synthesize sulfonamides using primary amines and sulfonylating agents.
- A solvent in the Pd-catalyzed cascade Suzuki-Heck reaction.
