说明

一般說明

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.

應用

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)

特點和優勢

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.
