2-(Di-t-butylphosphino)-3-methoxy-6-methyl-2',4',6'-tri-i-propyl-1,1'-biphenyl

Ligand used in the palladium-catalyzed C-O bond forming reactions of secondary and primary alcohols with a range of aryl halides. Heterocyclic halides and, for the first time, electron-rich aryl halides can be coupled with secondary alcohols.

Rockpahos is commonly used as a catalyst in organic reactions along with a palladium compound catalyst.

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.
