| Application: | 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. |
| Application: | 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. |
