2-di-tert-butylphosphino-2,4',6'-triisopropylbiphenyl Description
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.
2-di-tert-butylphosphino-2,4',6'-triisopropylbiphenyl Application
tBuXPhos has been used in the preparation of [
tBuXPhosAu(MeCN)]BAr
4F, a gold catalyst for the intermolecular [2+2] cycloaddition of terminal arylalkynes with substituted alkenes to form functionalized cyclobutenes with high regioselectivity.
