WebMar 16, 2024 · A BiPhenPhos-like bidentate ligand (L1), of which the chiral form has been successfully utilized to the branched-selective and enantioselective N-acetyl directed … 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. Originally described by workers at Union Carbide, it has become a standard ligand in hydroformylation.
