Description

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.

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.
