Application

RockPhos is a biphenyl-based phosphine ligand used with Pd(0) catalyst for carbon-carbon and carbon-heteroatom bond formation reactions.
It can also be employed in the:
  • 2-fluroethoxylation of bromo-chalcones in the presence of palladium catalyst.
  • Conversion of aryl chlorides into aryl methoxides using RockPhos Pd G3 as a catalyst.
