| Application: | Diethylamine can be used as:• A catalyst in the tandem Knoevenagel-Michael reaction of dimedone with aromatic aldehydes to synthesize bis-dimedone derivatives. • A solvent to synthesize 4-quinolones via Sonogashira cross-coupling of iodoanilines and alkynes. • A base in the desymmetrizing cyclization of benzylic diallyl iodide to synthesize methylene indanes via intramolecular Heck reaction. • A template in the synthesis of silicoaluminophosphate (SAPO) molecular sieves. |
| General description: | Diethylamine is a secondary amine that is used in the production of pesticides, dyes, rubber, resins, and pharmaceuticals as a solvent, catalyst, and corrosion inhibitor. |
