Recommanded Product: 175136-62-6. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Tris(3,5-bis(trifluoromethyl)phenyl)phosphine, is researched, Molecular C24H9F18P, CAS is 175136-62-6, about Effect of Ligand Modification on Rhodium-Catalyzed Homogeneous Hydroformylation in Supercritical Carbon Dioxide. Author is Palo, Daniel R.; Erkey, Can.
Several fluoroalkyl- and fluoroalkoxy-substituted tertiary arylphosphines were synthesized and studied in the homogeneous catalytic hydroformylation of 1-octene using HRh(CO)L3 (L = tertiary arylphosphine). The activity of the Rh complex (formed in situ from Rh(CO)2(acac) and L) increased with decreasing basicity of the phosphine according to the series [3,5-(CF3)2C6H3]3P > [4-CF3C6H4]3P ≈ [3-CF3C6H4]3P > [4-CF3OC6H4]3P > [4-F(CF2)4(CH2)3C6H4]3P. The very weakly basic phosphine (C6F5)3P did not complex with Rh(CO)2(acac), most likely due to a combination of electronic and steric factors. Steric effects did not play a role in either the activity or selectivity of the Rh catalysts that were formed under hydroformylation conditions.
This literature about this compound(175136-62-6)Recommanded Product: 175136-62-6has given us a lot of inspiration, and I hope that the research on this compound(Tris(3,5-bis(trifluoromethyl)phenyl)phosphine) can be further advanced. Maybe we can get more compounds in a similar way.
