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.
Different reactions of this compound(Tris(3,5-bis(trifluoromethyl)phenyl)phosphine)HPLC of Formula: 175136-62-6 require different conditions, so the reaction conditions are very important.
