Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 175136-62-6, is researched, Molecular C24H9F18P, about The electron-poor phosphines P{C6H3(CF3)2-3,5}3 and P(C6F5)3 do not mimic phosphites as ligands for hydroformylation. A comparison of the coordination chemistry of P{C6H3(CF3)2-3,5}3 and P(C6F5)3 and the unexpectedly low hydroformylation activity of their rhodium complexes, the main research direction is crystal structure platinum fluoromethylphenylphosphine chloro complex; fluoroarylphosphine coordination palladium platinum rhodium iridium; hydroformylation catalyst rhodium fluoroarylphosphine; phosphite analog fluoroarylphosphine ligand rhodium hydroformylation catalyst.Quality Control of Tris(3,5-bis(trifluoromethyl)phenyl)phosphine.
The fluoroaryl phosphines P{C6H3(CF3)2-3,5}3 (La) and P(C6F5)3 (Lb) form trans-[MCl2(La)2] and trans-[MCl2(Lb)2] (M = Pd or Pt) which were isolated and fully characterized. 31P NMR studies of competition experiments show that the stability of trans-[PdCl2L2] is in the order L = Lb < La < PPh3. The crystal structure of trans-[PtCl2(La)2] is reported and reveals that the Pt-P bond lengths in trans-[PtCl2L2] are in the order L = Lb < La < PPh3. The equilibrium established when [Pt(norbornene)3] is treated with La or Lb were studied by 31P and 195Pt NMR spectroscopy and [PtLn(norbornene)3-n] (n = 1-3) identified. Ligands La and Lb appear to have similar affinities for Pt(0). Trans-[MCl(CO)(La)2] and trans-[MCl(CO)(Lb)2] (M = Rh or Ir) were synthesized and fully characterized; the values of νCO are comparable with those for analogous phosphite complexes. The ligands La, Lb, P(C6H2F3-3,4,5)3 (Lc), P{C6H4(CF3)-2}3 (Ld), PPh3 and P(OPh)3 were tested in Rh-catalyzed hydroformylation of 1-hexene and La, Lb, and PPh3 were tested in Rh-catalyzed hydroformylation of 4-methoxystyrene. Ligands La and Lb are stable under the hydroformylation catalysis conditions. For the 1-hexene reaction, the activity and selectivity for La and Lc are very similar to the PPh3 catalyst (TOF ∼400 h-1; n:iso 2.5-3.0), but for the sterically demanding Lb and Ld the activity and selectivity was much lower than with PPh3 (TOF ∼15, n:iso ratio 0.6). Thus, the yield of heptanals obtained with the catalyst derived from La is 94% while under the same conditions with Lb only 6%. The TOF for the La/Rh catalyst was 5 times lower than for the P(OPh)3/Rh catalyst despite the superficially similar ligand electronic characteristics for La and P(OPh)3. There is still a lot of research devoted to this compound(SMILES：FC(C1=CC(C(F)(F)F)=CC(P(C2=CC(C(F)(F)F)=CC(C(F)(F)F)=C2)C3=CC(C(F)(F)F)=CC(C(F)(F)F)=C3)=C1)(F)F)Quality Control of Tris(3,5-bis(trifluoromethyl)phenyl)phosphine, and with the development of science, more effects of this compound(175136-62-6) can be discovered.
