Opis

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.
