Description

Application

N-XantPhos is a deprotonatable chelating aryldiphosphine ligand that can be used in:

• The preparation of Pd-NiXantphos catalyst system for the room temperature cross-coupling reactions of unactivated aryl chlorides.
• The synthesis of cinchonine iridium(III) cyclometalated complex that exhibits luminescence and good quantum efficiency.
• N-XantPhos and N-modified counterparts are also used in the preparation of rhodium based catalysts for hydroformylation reaction.
