XPhos [2-Dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl] is an air-stable electron-rich biaryl monophosphine ligand² developed by the Buchwald group to enhance the reactivity of palladium catalysis during cross-coupling reactions.

Zastosowanie

Ligand for increased scope of Pd-catalyzed amination and amidation via arene sulfonates, aryl halides.

Ligand used in a Pd-catalyzed Suzuki coupling leading to C-15 analogs of vindoline.
Direct annulation of 2-haloanilines to indoles and tryptophans catalyzed by Pd. Synthesis of regioregular polythiophenes.

Preferred ligand for greener Sonogashira coupling in TPGS-750-M.

Preferred ligand for greener Sonogashira coupling in TPGS-750-M.

For small scale and high throughput uses, product is also available as ChemBeads (928364)

On the Way Towards Greener Transition-Metal-Catalyzed Processes as Quantified by E Factors

XPhos may be used as a ligand in the following reactions:

• Preparation of functionalized benzylic sulfones via palladium-catalyzed Negishi cross-coupling between alkyl sulfones and aryl halides.
• Along with pre-milled palladium(II) acetate as a pre-catalyst for the Stille cross-coupling of aryl chlorides with tributylarylstannanes to form the corresponding biaryl compounds.
• Along with platinum chloride to catalyze the hydrosilylation of terminal arylalkynes with silanes to form functionalized β-(E)-vinylsilanes.
