Description

General description

XPhos Pd G2 is a bulky monodentate biaryl ligand.[1] It is a Buchwald′s 2^nd generation preformed catalyst.[2] It undergoes rapid reductive elimination to form a reactive, monoligated Pd(0) species.[1]

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.[2]
• Suzuki-Miyaura cross-coupling reactions of sensitive aryl and heteroarylboronic acids.[1]
• Synthesis of potassium Boc-protected secondary aminomethyltrifluoroborates, via Suzuki-Miyaura cross-coupling reaction.[3]

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