Beschreibung

Allgemeine Beschreibung

Lithium bis(trimethylsilyl)amide is a non-nucleophilic strong Brønsted base, which is generally soluble in most of the nonpolar organic solvents. It is most commonly employed in organic reactions.

Anwendung

Base employed in generating enolates for the preparation of lactone precursors, pyranones, and cyclohexanes. Used to catalyze the addition of phosphine P-H bonds to carbodiimides leading to phosphaguanidines.[6] Also used in a novel three-step synthesis of disubstituted 1,2,5-thiadiazoles. For general uses, product is also available in powdered form (324620)

Leistungsmerkmale und Vorteile

ChemBeads are chemical coated glass beads. ChemBeads offer improved flowability and chemical uniformity perfect for automated solid dispensing and high-throughput experimentation. The method of creating ChemBeads uses no other chemicals or surfactants allowing the user to accurately dispense sub-milligram amounts of chemical.
