Application

HandaPhos is a monophosphine ligand. As reported by Lipshutz and coworkers, HandaPhos, in tandem with designer surfactant TPGS-750-M, allows for palladium-catalyzed cross-couplings to be performed at room temperature requiring levels of palladium lower than 1000 ppm (less than 0.1 mol %). HandaPhos can be used in cross-couplings such as Suzuki-Miyaura, Sonogashira, Buchwald-Hartwig and several other commonly used cross-coupling reactions.
