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. It is used as a plasticizer and a fire retardant in a wide variety of settings and products. [3]
Ph 3 PO is structurally related to POCl 3. [2] As established by X-ray crystallography, the geometry around P is tetrahedral, and the P-O distance is 1.48 Å. [3] Other modifications of Ph 3 PO have been found: For example, a monoclinic form crystalizes in the space group P2 1 /c with Z = 4 and a = 15.066(1) Å, b = 9.037(2) Å, c = 11.296(3) Å, and β = 98.47(1)°.The orthorhombic ...
The phosphorus-containing product is triphenylphosphine sulfide, Ph 3 PS. This reaction can be employed to assay the "labile" S 0 content of a sample, say vulcanized rubber. Triphenylphosphine selenide, Ph 3 PSe, may be easily prepared via treatment of PPh 3 with red (alpha-monoclinic) Se. Salts of selenocyanate, SeCN −, are used as the Se 0 ...
The Michaelis–Arbuzov reaction is the chemical reaction of a trivalent phosphorus ester with an alkyl halide to form a pentavalent phosphorus species and another alkyl halide. Commonly, the phosphorus substrate is a phosphite ester (P(OR) 3) and the alkylating agent is an alkyl iodide. [11] The mechanism of the Michaelis–Arbuzov reaction
Alachlor mixes well with other herbicides. It is marketed in mixed formulations with atrazine, glyphosate, trifluralin and imazaquin.It is a selective, systemic herbicide, absorbed by germinating shoots and by roots.
Triphenyl phosphite ozonide (TPPO) is a chemical compound with the formula PO 3 (C 6 H 5 O) 3 that is used to generate singlet oxygen. [ 1 ] [ 2 ] When TPPO is mixed with amines , the ozonide breaks down into singlet oxygen and leaves behind triphenyl phosphite . [ 2 ]
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 dichloride, (C 6 H 5) 3 PCl 2, is a chlorinating agent widely used in organic chemistry. Applications include the conversion of alcohols and ethers to alkyl chlorides, the cleavage of epoxides to vicinal dichlorides and the chlorination of carboxylic acids to acyl chlorides. [2]
