Beschreibung

Anwendung

RockPhos is a biphenyl-based phosphine ligand used with Pd(0) catalyst for carbon-carbon and carbon-heteroatom bond formation reactions.[1][2]
It can also be employed in the:

• 2-fluroethoxylation of bromo-chalcones in the presence of palladium catalyst.[2]
• Conversion of aryl chlorides into aryl methoxides using RockPhos Pd G3 as a catalyst.[3]
