Thermal stability of primary and secondary phosphine oxides formed as a reaction of phosphine oxide with ketones
漏 2016 Taylor & Francis Group, LLC.We present the study of reactivity of electrochemically generated in situ from white phosphorus P4 phosphine oxide H3PO toward various ketones (acetone, methylethylketone, methyl-n-propylketone). This interaction was found to give a selective formation of mono- and bis-(伪-oxyalkyl)phosphine oxides RR使C(OH)P(O)H2 (1) and (RR使C(OH))2P(O)H (2) where R = Me; R使 = Me, Et, n-Pr. Thermal properties of the formed primary and secondary phosphine oxides have been studied and quantum chemical calculations of thermodynamic stability of these compounds were performed
Reactivity of phosphine oxide H<inf>3</inf>PO in the reactions with ketones
漏 2016, Springer Science+Business Media New York.The reactivity of the electrochemically generated phosphine oxide H3PO towards ketones (acetone, ethyl methyl ketone, methyl n-propyl ketone, and tert-butyl methyl ketone) has been studied. It was found that this reaction led to the formation of mono- and bis(hydroxyalkyl)phosphine oxides of the formulas RR膯(OH)P(O)H2 and [RR膯(OH)]2P(O)H (R = Me; R麓 = Me, Et, Pr) and represents the first example of the P鈥擟 bond formation involving the intermediate H3PO
Novel effectively carbonaceous and sulfurated hydrogen corrosion inhibitors on the basis of organosulfurphosphorus compounds
Novel ammonium salts of O,O-dialkyl dithiophosphoric acids were obtained by one-pot synthesis from white phosphorus, elemental sulfur, industrial alcohols or phenols, and amines. Long-chain S-alkyl O,O-dialkyldithiophosphonates were prepared by the reaction of red phosphorus with elemental sulfur, alcohols, and the cheap industrial fractions of C16-C18 and C 20-C26 of higher 伪-olefins in the presence of Lewis acid catalyst. The dithiophosphates obtained possess the high anticorrosion activities toward mild steel. 漏 2013 Copyright Taylor and Francis Group, LLC
Polymorphism and thermodynamic properties of chloro(cyclopentadienyl)bis(triphenylphosphine)ruthenium(II) complex
漏 2016 Elsevier B.V. All rights reserved. A new crystalline polymorph of known chloro(cyclopentadienyl)bis(triphenylphosphine)ruthenium(II) complex [RuCl(PPh3)2(畏5-C5H5)] was obtained and characterized by various analytical methods including single-crystal and powder X-ray diffraction (XRPD) and differential scanning calorimetry (DSC) in combination with thermo-gravimetric analysis (TG-DSC). The obtained crystals of new polymorph are monoclinic, space group P21/n, with a = 11.125(4), b = 19.184(6), c = 15.946(5) 脜, 伪 = 90, 尾 = 100.174(5), 纬 = 90, and Z = 4. It has been found that real melting point of the complex (M.p. = 252-253 掳C) can be determined only in inert atmosphere while an apparent melting is observed in the range 142-150 掳C due oxygen promoted oxidative dissociation of triphenylphosphine ligand
