Triethylamine is the chemical compound with the formula N(CH2CH3)3, commonly abbreviated Et3N. It is also abbreviated TEA, yet this abbreviation must be used carefully to avoid confusion with triethanolamine or tetraethylammonium, for which TEA is also a common abbreviation. It is a colourless volatile liquid with a strong fishy odor reminiscent of ammonia. Like diisopropylethylamine (Hünig's base), triethylamine is commonly employed in organic synthesis, usually as a base.

WebApr 1, 2024 · From the point of view of chemical structures (Fig. 1), TEA and DIPA are common secondary and tertiary amines with pKa values around 11 while TMG, a guanidine related compound, has a pKa at 14–15 [22, 23]. Due to its stronger basicity, TMG tends to be adsorbed on GC columns more severely than the two other amines. WebStudy Notes. The lone pair of electrons on the nitrogen atom of amines makes these compounds not only basic, but also good nucleophiles. Indeed, we have seen in past chapters that amines react with electrophiles in several polar reactions (see for example the nucleophilic addition of amines in the formation of imines and enamines in Section 19.8).
