General Description

"(2-diphenylphosphorylethyl-phenyl-phosphoryl)benzene" is a complex, synthetic chemical compound that features a benzene ring as a core structural component. It contains multiple functional groups including two phenylphosphoryl groups attached to the benzene ring and an ethyl chain. These bondings involve phosphorus atoms, a central feature of organophosphorus compounds. This chemical might find application in research, laboratories or chemical industries. However, information about its specific properties, toxicity, usage, or practical applications may not be readily accessible as it is quite uncommon and specific synthesis would be required to create this compound. The presence of multiple phenyl and phosphoryl groups suggests that it could be involved in chemical reactions as a potential reagent, catalyst, or for forming coordination complexes. However, the exact role would depend on the context of the chemical reaction or process in question.

A salt-free synthesis of 1,2-bisphosphorylethanes via an efficient PMe3-catalyzed addition of >P(O)H to vinylphosphoryl compounds

Abstract A convenient and versatile method was developed for the preparation of 1,2-bisphosphorylethanes. Thus, in the presence of a catalytic amount of trimethylphosphine, a variety of >P(O)H compounds efficiently add to vinylphosphoryl compounds to produce the corresponding 1,2-bisphosphorylethanes in high yields. In most cases, the trimethylphosphine catalyst was simply removed under vacuum leaving spectroscopically pure adducts. The present method provided a halogen and metal-free clean process for the preparation of 1,2-bisphosphorylethanes.

The Trityl-Cation Mediated Phosphine Oxides Reduction

Reduction of phosphine oxides into the corresponding phosphines using PhSiH3 as a reducing agent and Ph3C+[B(C6F5)4]? as an initiator is described. The process is highly efficient, reducing a broad range of secondary and tertiary alkyl and arylphosphines, bearing various functional groups in generally good yields. The reaction is believed to proceed through the generation of a silyl cation, which reaction with the phosphine oxide provides a phosphonium salt, further reduced by the silane to afford the desired phosphine along with siloxanes. (Figure presented.).

Novel Bis[N-alkyl-N-(2-diphenylphosphinylethyl)]diglycolamides: Synthesis and NMR Spectroscopy Studies

Abstract: Pentadentate bis[N-alkyl-N-(2-diphenylphosphinylethyl)]diglycolamides [Ph2P(O)CH2CH2N(R)· C(O)CH2]2O, where R Me, Bu, Oct, were synthesized by reaction of diglycolyl chloride with N-alkyl-N-(2-diphenylphosphinylethyl)amines Ph2P(O)CH2CH2NHR obtained by reacting diphenyl(2-phenoxyethyl)phosphine oxide with primary alkylamines in DMSO in the presence of an aqueous alkali. Structure of the prepared compounds was studied by 1H, 13C, and 31P NMR spectroscopy.

Acetylacetonate and Acetate Complexes of Nickel(II) Catalyse the Air Oxidation of Phosphines

The polymeric complex trans-[Ni(acac)2(μ2-dppe)]n·2MeCN {1a, dppe = 1,2-ethylenebis(diphenylphosphine)} is sometimes transiently deposited from the reaction of [Ni(acac)2] with dppe in MeCN prior to its facile onwards air oxidation to final crystallization of a doubly-oxygenated relative, cis-[Ni(acac)2(μ2-dppeO2)]n {2, dppeO2 = 1,2-ethylenebis(diphenylphosphineoxide)}. A similar unsolvated phase of the initial polymer, trans-[Ni(acac)2(μ2-dppe)]n (1b), can be isolated from toluene. The oxidation of dppe by O2 is catalytic and dppeO2 was isolated in close to stoichiometric yields from solutions containing 5 % Ni(acac)2 relative to dppe. The reaction rate slows after a few turnovers due to inhibition by the product. The relative yields of dppeO2 are higher than those from catalytic air oxidation of methyldiphenylphosphine and triphenylphosphine and we speculate that a pathway for this reaction involves a dimetallic cooperativity enabled specifically by dppe.
