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.

We compared the performances of five commercial rubella virus immunoglobulin G (IgG) avidity assays. The Adaltis (kappa = 0.28) and Diesse (kappa = 0.33) assays showed poor correlation, the Behring assay (kappa = 0.68) showed good correlation, and the Euroimmun

Recent findings suggest that hypercholesterolemia may contribute to the onset of Alzheimer's disease-like dementia but the underlying mechanisms remain unknown. In this study, we evaluated the cognitive performance in rodent models of hypercholesterolemia in relation to neuroinflammatory changes and amyloid
