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.

Pages 10-14 View PDF. Article preview. WebHydroformylation, or Oxo Synthesis, is used for the production of aldehydes from alkene compounds. The reaction is catalyzed by organorhodium or organocobalt compounds and adds a hydrogen atom to the C=C bond to form a C-C bond and a formyl group to the molecule, creating an aldehyde. Aldehyde compounds formed by hydroformylation are …
WebNov 7, 1996 · The kinetics of biphasic hydroformylation of 1-octene has been studied in the presence of ethanol cosolvent, using water-soluble Rh/TPPTS as a catalyst. The rate was found to be first order with catalyst and olefin concentrations and fractional order with hydrogen concentration. The rate versus CO concentration passed through a maximum, …
