BiPhePhos is an organophosphorus compound that is used as a ligand in homogeneous catalysis. Classified as a diphosphite, BiPhePhos is derived from three 2,2'-biphenol groups, which constrain its shape in such a way to confer high selectivity to derived catalysts.[1] Originally described by workers at Union Carbide,[2] it has become a standard ligand in hydroformylation.[3][4]
