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.
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.
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 ...
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.
Triphenylarsine is the chemical compound with the formula As(C 6 H 5) 3.This organoarsenic compound, often abbreviated AsPh 3, is a colorless crystalline solid that is used as a ligand and a reagent in coordination chemistry and organic synthesis.
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.
