Lashkhi, V. L. published the artcileAntiwear action of organophosphorus and chloroorganophosphorus compounds in lubricating oils, Category: chlorides-buliding-blocks, the publication is Khimiya i Tekhnologiya Topliv i Masel (1975), 47-50, database is CAplus.

Antiwear additives with high thermal adsorption properties, such as CCl3(CH2)6PO(OEt)2 [53280-04-9] were effective for friction at low contact loads and low sliding rates. Others, such as CCl3PO(OEt)2 [866-23-9], PhPO(OCH2CCl3)2 [18255-20-4], and CCl3PO(OBu)2 [5887-93-4], forming strong superficial films, were effective for high sp. loads and high velocities. The additive CCl3C6H4PO(OEt)2 [28652-49-5], had simultaneously high thermal adsorption and gave strong films. The higher the work function of the metal electron, the higher was the efficiency of the additive. The esters of phosphonic acids, with or without Cl and having low chem. activity for a metal, were ineffective antiwear additives.

Sanin, P. I. published the artcileInteraction of antiwear additives with friction surfaces, Product Details of C5H10Cl3O3P, the publication is Wear (1974), 30(2), 249-56, database is CAplus.

A study of the effects of phosphonic acid esters on frictional wear under diverse loads and sliding speeds indicated that the efficiency of such phosphonates (I) as antiwear additives depends on their structure and varies with the frictional modes. Principal I were grouped as esters which are ineffective under both high and low loads (esters with no Cl atoms); esters effective under both high and low loads (CCl3-group containing esters); and esters effective under high or low loads. The interaction of I with steel has been studied. Dissimilarity in the efficiency of esters as lubricating oil additives is explained by their different adsorption and chem. actions.

Gramstad, Thor published the artcileStudies of hydrogen bonding. Part XXVIII. Hydrogen bond association of phenol with 5,5-dimethyl-2-oxo-1,3,2-dioxaphosphorinanes and diethylphosphonates, SDS of cas: 866-23-9, the publication is Acta Chemica Scandinavica, Series B: Organic Chemistry and Biochemistry (1977), B31(5), 345-53, database is CAplus.

The association constant and enthalpy of formation of the equilibrium between phenol and twelve 5,5-dimethyl-2-oxo-1,3,2-dioxaphosphorinanes I (R = Cl, CCl3, OMe, Ph, NMe2, etc.) and six diethylphosphonates (EtO)2P(O)R1 (R1 = CCl3, SMe, CPh3, etc.) were determined The association constant, enthalpy of association, half band width, ν1/2, of the complexed O-H bond, P(O) bond moment, μPO, and excess charge d., Δq, on the phosphoryl O give linear relations with the O-H frequency shift, ΔνOH. The calculated P(O) bond moment in the axial and equatorial position gives a linear correlation with the exptl. P(O) stretching frequency. Furthermore, the square root of the addnl. dipole moment, Δμ1/2, due to H bond formation, correlates linearly with the association constant, the O-H frequency shift, and with the half band width. A close relationship between band width of the complexed O-H bond and the strength and polarity of the H bonded complex is deduced.

Griffiths, W. Richard published the artcileThe mass spectra of phosphonyl compounds. Part 3. Dimethyl- and diethylalkane and substituted-methane phosphonates, Category: chlorides-buliding-blocks, the publication is Phosphorus and Sulfur and the Related Elements (1978), 5(1), 101-6, database is CAplus.

The electron impact spectra of 28 related phosphonates were determined Et, Me₂CH, and Me₃C groups which are bound directly to P, fragment to the corresponding alkenes; similar Me₂CH, Me₃C groups in the di-Me esters also fragment to ethylene and propene, resp., i.e., the P-alkyl rearranges with transfer of the elements of a Me group to the P ion. The di-Et alkenephosphonates undergo double H rearrangements of an ethoxy group to give dihydroxyphosphonium ions. The di- and trihydroxyphosphonium ions have a characteristic fragmentation which involves loss of water. This characteristic has been used as evidence for the rearrangement of a phosphacylium ion to a dihydroxyphosphonium ion.

Van Tilborg, W. J. M. published the artcileThe electrochemical Wittig-Horner reaction; evidence of a stepwise cleavage of a four-membered ring Wittig intermediate, Application In Synthesis of 866-23-9, the publication is Recueil des Travaux Chimiques des Pays-Bas (1980), 99(6), 202-6, database is CAplus.

Electroreduction of diethyl(trichloromethyl)phosphonate in the presence of aldehydes or ketones replaces the O atom of the carbonyl group by a dichloromethylene group. The yield of 1,1-dichloroethene product decreases substantially if the carbonyl compound carries strongly acidic hydrogen. In several cases the conversion of the 4-membered ring Wittig intermediate into its corresponding carbanion by heterolytic P-C bond cleavage was observed The intermediate carbanion is sufficiently stable to be intercepted by proton abstraction. These observations suggest that the decomposition of the Wittig 4-membered ring intermediate occurs along a 2-step pathway.

Yuan, Hai published the artcileStructural modifications of (1S,3S)-3-amino-4-difluoromethylenecyclopentanecarboxylic acid, a potent irreversible inhibitor of GABA aminotransferase, Quality Control of 866-23-9, the publication is Bioorganic & Medicinal Chemistry Letters (2007), 17(6), 1651-1654, database is CAplus and MEDLINE.

Low brain levels of the inhibitory neurotransmitter γ-aminobutyric acid (GABA) lead to convulsions. Inhibition of GABA aminotransferase increases the concentration of GABA and can terminate the convulsions. Earlier we reported the synthesis of (1S,3S)-3-amino-4-difluoromethylenecyclopentanecarboxylic acid (2), which is 186 times more potent an inactivator of GABA aminotransferase than the epilepsy drug S-vigabatrin. The corresponding dichloromethylene analog of 2 (compound 3) has been made, but it shows only weak reversible inhibition of GABA aminotransferase. However, the tetrazole isostere of 2 (compound 4) has been found to be a time-dependent inactivator of GABA aminotransferase. Although it is 20 times less potent than carboxylic acid 2, it is 2.5 times more potent than S-vigabatrin. A calculation of the Clog P values indicates that 4 is the most lipophilic of the three, being 69 times more lipophilic than 2 and 55 times more lipophilic than S-vigabatrin, indicating potential for improved bioavailability.
