Descrizione generale

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.

Applicazioni

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

A polysaccharide-based chiral stationary phase (Sepapak-4), with cellulose tris(4-chloro-3-methylphenylcarbamate) as chiral selector, has been investigated in liquid chromatography (LC). Its enantioresolution power was evaluated towards 13 basic amino-drugs with widely different structures and polarities, using polar organic mobile phases. After

Second-order rate constants of the diethylamine-promoted enantiomerization of 2-[2-(1-methyl-1H-pyrrol-2-yl)-2-oxo-1-phenylethyl]-isoindole-1,3-dione, a chiral alpha-substituted ketone endowed with high anti-MAO activity type-A, were measured by dynamic high-performance liquid chromatography (DHPLC), stopped-flow high-performance liquid chromatography (sf-HPLC), and a classical method based on enantioselective HPLC
