4,6-Bis(diphenylphosphino)-10H-phenoxazine

4,6-Bis(diphenylphosphino)-10H-phenoxazine, commonly known as nixantphos, is a bidentate phosphine ligand featuring a rigid phenoxazine backbone. It is widely employed in transition-metal-catalyzed cross-coupling reactions due to its electron-rich and sterically bulky properties.
