Beschreibung

Allgemeine Beschreibung

XPhos Pd G2 is a bulky monodentate biaryl ligand. It is a Buchwald′s 2nd generation preformed catalyst. It undergoes rapid reductive elimination to form a reactive, monoligated Pd(0) species.

For larger scale uses, product also available in powdered form (741825)

Anwendung

XPhos Pd G2 was employed as catalyst in the following reactions:

• Palladium-catalyzed Suzuki-Miyaura coupling reactions of potassium organotrifluoroborates and sulfamates.
• Suzuki-Miyaura cross-coupling reactions of sensitive aryl and heteroarylboronic acids.
• Synthesis of potassium Boc-protected secondary aminomethyltrifluoroborates, via Suzuki-Miyaura cross-coupling reaction.

2nd Generation Buchwald Precatalysts

• Widely used for Suzuki-Miyaura cross-coupling reactions
• 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.
