Triphenylphosphine (IUPAC name: triphenylphosphane) is a common organophosphorus compound with the formula P(C 6 H 5) 3 and often abbreviated to P Ph 3 or Ph 3 P. It is versatile compound that is widely used as a reagent in organic synthesis and as a ligand for transition metal complexes, including ones that serve as catalysts in organometallic ...
Triphenylphosphine oxide (often abbreviated TPPO) is the organophosphorus compound with the formula OP(C 6 H 5) 3, also written as Ph 3 PO or PPh 3 O (Ph = C 6 H 5). It is one of the more common phosphine oxides. This colourless crystalline compound is a common but potentially useful waste product in reactions involving triphenylphosphine.
Another potential treatment being researched is the Class III anti-arrhythmic agents. Hyperkalemia of the tissue is one of the symptoms associated with OP poisoning. While the cellular processes leading to cardiac toxicity are not well understood, the potassium current channels are believed to be involved.
Treatment of this species with hydroxylamine in the presence of Ph 3 P results in replacement of the two single P–Cl bonds in Ph 3 PCl 2 by one double P=N bond: 2 Ph 3 PCl 2 + NH 2 OH·HCl + Ph 3 P → [(Ph 3 P) 2 N]Cl + 4HCl + Ph 3 PO. Triphenylphosphine oxide Ph 3 PO is a by-product. Bis(triphenylphosphine)iminium chloride is described as ...
Tetrakis(triphenylphosphine)palladium(0) is widely used to catalyse C-C coupling reactions in organic synthesis, see Heck reaction. Wilkinson's catalyst , RhCl(PPh 3 ) 3 is a square planar Rh(I) complex of historical significance used to catalyze the hydrogenation of alkenes.
The methylation of triphenylphosphine is the first step in the preparation of the Wittig reagent. Illustrative phosphorus(V) compounds: the phosphonium ion P(CH 2 OH) 4 +, two resonance structures for the Wittig reagent Ph 3 PCH 2, and pentaphenylphosphorane, a rare pentaorganophophorus compound. The parent phosphorane (σ 5 λ 5) is PH 5 ...
Triphenyl phosphate exhibits low acute toxicity by dermal or oral contact. [3] However, an increasing number of studies have linked exposure to TPhP with reproductive and developmental toxicity, neurotoxicity, metabolic disruption, endocrine effects, and genotoxicity. [6] [8] [9] TPhP has also been found to induce significant estrogenic activity.
Triphenylphosphine sulfide (IUPAC name: triphenyl-λ 5-phosphanethione) is the organophosphorus compound with the formula (C 6 H 5) 3 PS, usually written Ph 3 PS (where Ph = phenyl). It is a colourless solid, which is soluble in a variety of organic solvents.
