Uses

2-(Di-tert-butylphosphino)biphenyl (also known as JohnPhos) is a Buchwald ligand that is highly efficient in palladium-catalyzed reactions.

General Description

JohnPhos is a Buchwald′s sterically bulky biaryl phosphine ligand. It is a reactive dialkylbiaryl phosphine ligand which catalyzes the carbon-nitrogen bond-forming reactions. Coordination chemistry of gold catalysts bearing JohnPhos as ligand has been investigated by NMR spectroscopy.
