Phosphorous acid, triphenyl ester

1-Propanaminium, N-(2-aminoethyl)-N-(carboxymethyl)-2-hydroxy-N-(2-hydroxyethyl)-3-(phosphonooxy)-, N-C6-18 acyl derivs ., hydroxides, inner salts, disodium salts

Ethyl Triphenyl Phoshonium Bromide can also be a reactant for solid-state metathesis polycondensation to form alkyl-dipropenylthiophene monomers; and can also be used as a reactant for synthesis of D-amino acids from L-cysteine-derived thiazolidines.

Phosphonium, tetrabutyl-, salt with 1,1,2,2,3,3,4,4,4-nonafluoro-1-butanesulfonic acid (1:1)

Phosphorothioic acid, O,O,O-triphenyl ester

Phosphonic acid, [1,2-ethanediylbis[nitrilobis (methylene)]]tetrakis-, pentasodium salt

It is employed as a catalyst for the carboxylation of styrene oxide and as a reactant involved in epoxidation of arylalkenes, boration of allylic epoxides, Wittig reactions, selective dimerization of α-olefins, and synthesis of indoles. It has also been shown to be part of Phosphonium salts, having antiviral activity against influenza virus A.

Phosphonium bromide refers to a cationic quaternary organic phosphorus derivative with a bromide anion. Examples of phosphonium bromides include bromotriphenylphosphonium bromide, triphenyl(tetradecyl)phosphonium bromide, ethyltriphenylphosphonium bromide, etc. The alkylated phosphonium bromides are used as a precursor for the Wittig reagent, which is routinely used in alkene synthesis. The phosphonium bromides are also employed in the Kirsanov reaction to produce organophosphorus compounds normally employed as ligands and reagents. Phosphonium bromides are also involved in the Appel reaction, which converts alcohols into halides.

Phosphonium bromides, such as ethyltriphenylphosphonium bromide and tetrabutylphosphonium bromide, are employed as phase transfer catalysts (PTC) in the production of epoxy resins and powder coatings. They are also useful as pharmaceutical intermediates in several synthetic processes. Tetrabutylphosphonium bromide is also used in flavours and fragrances. Tetrabutylphosphonium bromide (TBPB) analogs are found to be muscarinic acetylcholine receptor (mAChRs) agonists. These receptors play a vital role in CNS and peripheral functions such as memory and attention mechanisms, motor control, nociception, regulation of sleep wake cycles, cardiovascular function, renal and gastrointestinal function (Nekoei, M., “A quantitative structure–activity relationship study of tetrabutylphosphonium bromide analogs as muscarinic acetylcholine receptors agonists”, J. Serb. Chem. Soc., 2011, 76 (8) 1117–1127).

Drying: when used to prepare , must be strictly dried immediately prior to use for best results. Drying can be achieved effectively by heating the flask containing the phosphonium salt at 110 °C/0.2 mmHg for several hours, or by repetitive (three times or more) azeotropic removal of water with benzene or toluene.

Phosphonic acid, [[(phosphonomethyl)imino]bis[2,1-ethanediylnitrilobis(methylene)]]tetrakis-, ammonium salt

AB - Introduction: A greater mitochondrial membrane potential in tumor cells has been shown to enhance the accumulation of triphenyl phosphonium derivatives. The aim of this study was to synthesize and characterize 99mTc- labeled alkyl triphenyl phosphonium (99mTc-Mito10-MAG3) for the early detection of breast tumors. Methods: Mito10-MAG3 was synthesized by coupling (10-aminodecyl)triphenyl phosphonium bromide with NHS-MAG3 and radiolabeled with 99mTc. Biodistribution and pharmacokinetics of 99mTc-Mito10-MAG3 was investigated in female Sprague-Dawley rats. Initially, 99mTc-Mito10-MAG3 was tested in animals with established breast tumors. In a subsequent longitudinal study, the imaging efficacy of 99mTc10-Mito- MAG3 for detecting small, nonpalpable breast tumors was assessed after chemically inducting breast carcinoma. Tumors detected by imaging were allowed to grow to palpable size and confirmed by histology. The results were compared with 99mTc-MIBI. Results: The synthesis of Mito10-MAG3 was confirmed by mass spectrometry. The compound was radiolabeled with 99mTc to >92% in a single step. The radiopharmaceutical exhibited fast blood clearance and low cardiac uptake. In the initial study, using animals with established breast tumors, 99mTc-Mito10-MAG3 imaging detected small lesions that were missed by palpation. In the longitudinal study, 99mTc-Mito10-MAG3 exhibited focal uptake in small breast tumors, which were confirmed by histology. Conclusions: Imaging, using 99mTc-Mito10-MAG3, allowed the early detection of small neoplastic lesions in the mammary glands. The agent significantly reduced cardiac uptake, compared with 99mTc-MBIB. The phosphonium-based derivatives warrant further characterization and development as imaging agents for scintimammography.

Quaternary phosphonium salts, obtained from tertiary alkylphosphines with the treatment with alkyl or aromatic halides, are replacing phase transfer catalysts and biocides functions for quaternary ammonium salts due to more effective performance and higher thermal stability. Phosphonium salts are used as epoxy curing agents.
