Description

Application

Triethylamine can be used as:

• An initiator for cracking heptane to yield ethylene and propylene.
• A catalyst to synthesize polysubstituted dihydrothiophenes via Domino ring-opening/recyclization reactions.
• A base in the Swern oxidation of primary and secondary alcohols to the corresponding carbonyl compounds.
• A solvent in the direct one-pot reductive imination of nitroarenes with aldehydes to synthesize imines.
