一般描述

rac-BINAP-Pd-G3 ChemBeads are a third generation (G3) Buchwald precatalyst on glass beads. It is an air, moisture and thermally-stable precatalyst and is highly soluble in a wide range of common organic solvents. It has long life in solutions. rac-BINAP-Pd-G3 ChemBeads are an excellent reagent for palladium catalyzed cross-coupling reactions. Some of thier unique features include lower catalyst loadings, shorter reaction time, efficient formation of the active catalytic species and accurate control of ligand: palladium ratio, relative to earlier generations of Buchwald precatalysts.

应用

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.For general uses, product is also available in powdered form (804967)
