Methanesulfonato(2-di-t-butylphosphino-2',4',6'-triisopropyl-1,1'-biphenyl)(2'-methylamino-1,1'-biphenyl-2-yl)palladium(II) (t-BuXPhos Pd G4) is a Buchwald fourth-generation palladacycle precatalyst featuring a t-BuXPhos ligand and a 2'-methylamino-1,1'-biphenyl-2-yl palladacycle core with a methanesulfonate counterion. It is a powerful precatalyst for classic cross-coupling reactions such as Suzuki-Miyaura, Buchwald-Hartwig amination, and C-N bond formation. The compound is bench-stable and soluble in most organic solvents. The t-BuXPhos ligand provides excellent steric and electronic properties for challenging coupling reactions. This precatalyst is part of the Buchwald Palladacycle Precatalyst Kit and is used in pharmaceutical synthesis and organic chemistry research.
