Rhodium-catalyzed hydroformylation of olefins: Effect of [bis(2,4-di-tert-butyl) pentaerythritol] diphosphite (alkanox P-24) on the regioselectivity of the reaction

Synthesis, characterization and coordination chemistry of a new phosphite–ether ligand: The effects of alkali metal salts and the ligand/Rh molar ratio on the catalytic activity and regioselectivity of a Rh(I) complex of this ligand in the hydroformylation of styrene

“…Among the most active and selective catalysts are Rh complexes of phosphite and bis(phosphite) ligands [3][4][5]. The phosphite and bis(phosphite) ligands are more resistant to oxidation [6] than are most of the other classes of phosphorus-donor ligands but are more weakly coordinating and degrade under catalytic reaction conditions [7].…”

Synthesis, Characterization, and DFT of a Novel Reactive Phosphorus Flame Retardant

“…Synthesis of the compound 7. The synthesis of the compound 4 was referred to these literatures [8][9][10]. The equal molar amounts of 2 and 3 were reacted in a flask while the by-product was distilled and the compound 4 was obtained.…”

Immobilization of a rhodium catalyst using a diphosphine-functionalized ionic liquid in RTIL for the efficient and recyclable biphasic hydroformylation of 1-octene

“…1,2 The most efficient catalysts reported for this reaction are rhodium complexes, and a large amount of work has been devoted to the improvement of reaction rates and selectivity by ligand design. 3,4 For example, monodentate and bidentate phosphorous-based ligands, [5][6][7][8][9][10][11] N-heterocyclic carbene (NHC), [12][13][14] and the hybrid P,O-or P,N-ligands with multiple ligations to the rhodium center, [15][16][17][18][19][20] have been synthesized by nely tuning their electronic and steric properties to spur the activity and selectivity of the rhodium complexes.…”
