Triphenyl phosphate (TPhP) is the chemical compound with the formula OP(OC 6 H 5) 3. It is the simplest aromatic organophosphate . This colourless solid is the ester (triester) of phosphoric acid and phenol .
Triphenyl phosphite is the organophosphorus compound with the formula P(OC 6 H 5) 3. It is a colourless viscous liquid. It is a colourless viscous liquid. Preparation
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 chemistry.
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.
The reaction mechanism of the Mitsunobu reaction is fairly complex. The identity of intermediates and the roles they play has been the subject of debate. Initially, the triphenyl phosphine (2) makes a nucleophilic attack upon diethyl azodicarboxylate (1) producing a betaine intermediate 3, which deprotonates the carboxylic acid (4) to form the ion pair 5.
A metal-phosphine complex is a coordination complex containing one or more phosphine ligands. Almost always, the phosphine is an organophosphine of the type R 3 P (R = alkyl, aryl).
Phosphites are oxidized to phosphate esters: P(OR) 3 + [O] → OP(OR) 3. This reaction underpins the commercial use of some phosphite esters as stabilizers in polymers. [6] Alkyl phosphite esters are used in the Perkow reaction for the formation of vinyl phosphonates, and in the Michaelis–Arbuzov reaction to form phosphonates.
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.
