Popis

General description

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

Application

2nd Generation Buchwald Precatalysts

• Widely used for Suzuki-Miyaura cross-coupling reactions

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.

For small scale and high throughput uses, product is also available as ChemBeads (927775)
