Descrizione

Descrizione generale

Cesium carbonate is a powerful inorganic base widely used in organic synthesis. It is a potential chemoselective catalyst for the reduction of aldehydes and ketones to alcohols. It is employed as base for the Heck coupling reaction of 4-trifluoromethyl-1-chlorobenzene and aryl chlorides.

Applicazioni

Cesium carbonate can be used as a base in C-C and C-N cross-coupling reactions such as Suzuki−Miyaura, Heck, and Buchwald-Hartwig amination reactions. It is also used as a base in alkylation reactions. Promotes the efficient O-alkylation of alcohols to form mixed alkyl carbonates.

For general uses, product is also available in powdered form(441902)

Caratteristiche e vantaggi

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.

• High-Throughput Reaction Screening with Nanomoles of Solid Reagents Coated on Glass Beads
• Versatile Methods to Dispense Sub-Milligram Quantities of Solids using Chemical Coated Beads for High-Throughput Experimentation
• ChemBead Enabled High-Throughput Cross-Electrophile Coupling Reveals a New Complementary Ligand
