Bimetallic platinum-ruthenium nanoparticles stabilized by pyridine- and monophosphine-based ligands were prepared either in supercritical CO2 or in THF. TEM analyses evidenced a tendency of the nanoparticles prepared in supercritical CO2 to agglomerate. Both types of bimetallic nanoparticles were further confined into functionalized multiwalled carbon nanotubes. Upon confinement, PtRu nanoparticles stabilized by phosphine ligands appeared more agglomerated than those stabilized by the pyridine ligand. These materials were applied to cinnamaldehyde hydrogenation. Confined PtRu nanoparticles showed higher catalytic activity and selectivity than unsupported nanoparticles.

Rhodium-catalyzed hydroformylation of 1,5-hexadiene to dialdehydes was investigated in compressed CO2 and in toluene using different fluorinated phosphine compounds as ligands at a temperature of 60 °C. Product yields depend greatly on the ligand used and, of the ligands examined, tris[3,5-bis(trifluoromethyl)phenyl]phosphine is the most effective for the production of dialdehydes both in supercritical CO2 (scCO2) and in toluene. The total yield of the dialdehydes passes through a min. at about 9 MPa as the CO2 pressure is increased and increases appreciably as the H2 pressure in scCO2 increases. The effect of the syngas (H2/CO) and H2 pressures on the reaction in scCO2 is different from that in toluene. It has been suggested that scCO2 promotes the hydroformylation reaction.

Electroneg. phosphine oxides were reduced to corresponding phosphines by trichlorosilane-mediated oxygen transfer to sacrificial PPh3 or P(OEt)3 with excellent yields. The diphosphine dioxides 2,2′-(Ar2PO)-1,1′-binaphthalene (1a-e, Ar = 3,5-(CF3)2C6H3, 4-CF3C6H4), Ar2POCH2CH2POAr2 (1g, Ar = C6F5), monophosphine oxides Ar3PO and Ar2PAr1 (1h and 1f, resp.; Ar = 3,5-(CF3)2C6H3, Ar1 = 1,1′-binaphthalene-2-yl) were deoxygenated to the corresponding phosphines (2a-h) by reaction with HSiCl3 in the presence of PPh3 or tri-Et phosphite, acting as sacrificial oxygen acceptors, which shift the deoxygenation reaction equilibrium to the corresponding phosphines. The advantage of the new method includes milder conditions and considerably shortened reaction times. Mechanistic studies about the oxygen transfer between the starting phosphine oxide and the sacrificial triphenylphosphine are also presented.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Evaluation of pressure and correlation to reaction rates during homogeneously catalyzed hydroformylation in supercritical carbon dioxide, published in 2008-08-31, which mentions a compound: 175136-62-6, mainly applied to hydroformylation octene supercritical carbon dioxide, Quality Control of Tris(3,5-bis(trifluoromethyl)phenyl)phosphine.

For the hydroformylation of 1-octene in supercritical carbon dioxide the relation between the change in pressure and the change in reaction mixture composition as a function of time was studied. The activity and selectivity was studied for the catalyst based on tris(3,5-bis(trifluoromethyl)phenyl)phosphine and rhodium(I) dicarbonyl acetylacetonate. The influence of the ligand to rhodium ratio on the hydroformylation was used to demonstrate how the pressure can be correlated to the conversion and yield. The initial rate of reaction is in good agreement with the initial pressure change in the batch reactor. Up to an aldehyde yield of 80%, the pressure drop appears to be independent of the reaction rate and selectivity. The highest average reaction rate, 7170 mol1-octeneoctene molRH-1 h-1, was obtained for a ligand to rhodium ratio of 50 and an initial concentration of 1-octene of 0.5 mol L-1. Both the reaction rate and the selectivity increase when the ligand to rhodium ratio is increased. The Peng-Robinson equation of state was used to describe the pressure as a function of the concentration of the reactants and products. The calculated pressure corresponds reasonably well with the observed reactor pressure. Following the progress of the reaction by monitoring the pressure is a good alternative to reaction mixture sampling, especially for fast reactions.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry.

In the presence of Pd2(dba)3, tris[3,5-bis(trifluoromethyl)phenyl]phosphine, triethylamine, and in some cases triethylammonium pentafluorobenzoate, O-pentafluorobenzoyl oxime esters such as I (F5Bz = C6F5CO) underwent aminoacylation, aminocarbonylation, aminoarylation, aminovinylation, and aminoalkynylation reactions with triethylammonium tetraarylborates, pinacoloboranes, or tributylstannanes to yield substituted pyrrolines such as II [R = Ph, 2-naphthyl, 4-MeC6H4, 2-thienyl, 4-MeOC6H4, 4-FC6H4, n-PrCC, 2-furanyl, 1-methyl-2-indolyl, 2-benzofuranyl, 1-(phenylsulfonyl)-3-indolyl, 1-Me-2-pyrrolyl, (E)-PhCH:CH, (E)-BuCH2CH2CH:CH, (E)-PhCH2CH:CH, PhCC, n-PrCC, cyclopropylethynyl, R1O (if X = CO); R1 = F3CCH2, Ph, PhCH2; X = bond, CO]. The method is predicated on generation of iminopalladium intermediates through oxidative addition of palladium into an electrophilic N-O bond, followed by cyclization with an alkene substituent and subsequent interception by aryl-, alkenyl-, or alkynylmetal reagents. For carbonylative processes, orchestrated protodecarboxylation of the pentafluorobenzoate leaving group underpinned the reaction efficiency; this process is likely a key feature in related Narasaka-Heck cyclizations and accounts for the efficacy of O-pentafluorobenzoyl oxime esters in aza-Heck reactions of this type. Reduction of three of the pyrrolines yielded substituted pyrrolidines such as III in 68-85% yields and in 4:1-10:1 dr.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Systematic Study of the Stereoelectronic Properties of Trifluoromethylated Triarylphosphines and the Correlation of their Behaviour as Ligands in the Rh-Catalysed Hydroformylation, published in 2021-01-27, which mentions a compound: 175136-62-6, mainly applied to phosphine triarylphosphine trifluoromethyl substituted preparation electronic property donicity; pi accepting property trifluoromethyl substituted triarylphosphine hydroformylation catalyst; phosphonium phosphine selenide coupling constant correlation donicity, HPLC of Formula: 175136-62-6.

The stereoelectronic properties of a series of trifluoromethylated aromatic phosphines have been studied using different approaches. The σ-donating capability has been evaluated by NMR (NMR) spectroscopy of the selenide derivatives and the protonated form of the different trifluoromethylated phosphines. The coupling constants between phosphorous and selenium (1JSeP) and phosphorous and hydrogen (1JHP) can be predicted by empirical equations and correlate the basicity of the phosphines with the number and relative position of trifluoromethyl groups. In contrast, the π-acceptor character of the ligands has been evaluated by measuring the frequency of the CO vibration in the IR (IR) spectra of the corresponding Vaska type iridium complexes ([IrCl(CO)(PAr3)2], PAr3 = triarylphosphine). Moreover, the correlation between the electronic properties and the performance of these phosphines as ligands in the rhodium-catalyzed hydroformylation of 1-octene has been established. Phosphines with the lowest basicity, that are those with the highest number of trifluoromethyl groups, gave rise to more active catalytic systems.

Author is Fast, Caleb D.; Jones, Caleb A. H.; Schley, Nathan D..

Cationic bis(phosphine)iridium complexes are found to catalyze the cleavage of cyclohexyl Me ethers by triethylsilane. Selectivity for C-O cleavage is determined by the relative rates of SN2 demethylation vs. SN1 demethoxylation, with the axial or equatorial disposition of the silyloxonium ion intermediate acting as an important contributing factor. Modulation of the electron-donor power of the supporting phosphine ligands enables a switch in selectivity from demethylation of equatorial Me ethers to 2° demethoxylation. Applications of these accessible catalysts to the selective demethoxylation of the 3α-methoxy group of cholic acid derivatives is demonstrated, including a switch in observed selectivity controlled by 7α-substitution. The resting state of the catalyst has been characterized for two phosphine derivatives, demonstrating that the observed switch in C-O cleavage selectivity likely results from electronic factors rather than from a major perturbation of the catalyst structure.

Author is Shaw, Megan H.; Whittingham, William G.; Bower, John F..

Urea-directed carbonylative insertion of Rh(I)-catalysts into one of the two proximal C-C bonds of aminocyclopropanes, e.g., I [R = Ph, OMe, NMe2, NMeOMe], generates rhodacyclopentanone intermediates, e.g., II. These are trapped by N-tethered alkynes to provide a (3+1+2) cycloaddition protocol that accesses N-heterobicyclic enones, e.g., III. Stoichiometric studies on a series of model rhodacyclopentanone complexes outline key structural features and provide a rationale for the efficacy of urea directing groups. A comprehensive evaluation of cycloaddition scope and a ‘second generation’ cationic Rh(I)-system, which provides enhanced yields and reaction rates for challenging substrates, are presented.
