WebMar 1, 2024 · The 6-DPPon ligand (L6) showed the best adipaldehyde selectivity (93 %) while the Biphephos ligand (L8) provided remarkably high reaction rate with a n/i ratio of 87. In sharp contrast, ligand L8 showed a rather low activity for butadiene hydroformylation ( Table 2 ).

WebOct 1, 2016 · The bulky chelating diphosphite ligand BiPhePhos was used for catalyst modification. Special emphasis was given to the transformation of the Rh-precursor … 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. graphic of a club

WebThe bisphosphite ligand, C46H44O8P2, is well known as Biphephos. One specific characteristic of this hydrido rhodium(I) monocarbonyl complex is that one bisphosphite ligand is coordinated in the expected bidentate mode and the other is coordinated in a monodentate mode. Thus, one phosphite moiety remains non-coordinating. graphic of a bathroom
