Aplicación

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.
