tBuXPhos [2-Di-tert-butylphosphino-2′,4′,6′-triisopropylbiphenyl] is an air-stable, electron-rich biaryl phosphine ligand developed by the Buchwald group to enhance the reactivity of palladium catalysis during cross-coupling reactions. tBuXPhos has been used in the preparation of [tBuXPhosAu(MeCN)]BAr4F, a gold catalyst for the intermolecular [2+2] cycloaddition of terminal arylalkynes with substituted alkenes to form functionalized cyclobutenes with high regioselectivity.
tBuXPhos is a ligand for Pd-catalyzed C-O and C-N bond formation.
It can be used in the following reactions:
• Palladium-catalyzed Tsuji-Trost substitution and cross-coupling of benzylic fluorides.
• Palladium-catalyzed C-N cross-coupling of sulfinamides and aryl halides.
• Palladium-catalyzed rapid methoxylation and deuteriomethoxylation of bromo-chalcones.
- Effective ligand for the Pd-catalyzed arylation of pyrazoles, indazoles and amino heterocycles.
- Ligand used in the Pd-catalyzed synthesis of phenols from aryl halides and KOH.
- Ligand used in the Pd-catalyzed of benzoic acids from aryl halides and CO2.
- Ligand used in the Pd-catalyzed trifluoromethylation of vinyl sulfonates.
- Ligand used in the Pd-catalyzed arylation of nitroacetates.
- Ligand used in the Pd-catalyzed Suzuki−Miyaura cross-coupling of allylboronates and aryl halides.
- Ligand used in the Pd-catalyzed cyanation of (hetero)arylchlorides and bromides.
- Ligand used in the Pd-catalyzed C–N cross coupling of sulfinamides and aryl halides.
- Ligand used in the Pd-catalyzed arylation of cyanamides.
