Data are presented on the methods of synthesis, structure, and physical and chemical properties of cyclic compounds of hexacoordinate phosphorus–Λ6-1, 3, 2-diheterophosphacyclanes, in which the phosphorus atom is incorporated ...

© 2016 Wiley Periodicals, Inc.The reaction of 2,4-diaryl 1,3,2,4-dithiadiphosphetane-2,4-disulfide with diketonide of d-mannitol has been found to give optically active bisaryldithiophosphonic acids transformed into the ...

For N-(thio)phosphorylthioureas of the common formula RC(S)NHP(X)(OiPr)2 HLI (R = N-(4′-aminobenzo-15-crown-5), X = S), HLII (R = N-(4′-aminobenzo-15-crown-5), X = O), HLIII (R = PhNH, X = S), HLIV (R = PhNH, X = O), and ...

The relationship between the structure and reactivity of compounds is one of the basic problems of organic and organoelement chemistry. On the basis of previously suggested models of steric and inductive substituents effects ...

Abstract-Ionization constants of a series of aminomethylphosphine oxides and respective amino precursors, as well as their isostructural amino phosphonates in water-2-propanol or water medium were determined. The main ...

N-(Thio)phosphorylated (thio)carbamides and (thi o)amides are proposed as modifiers of polymer nitrocellulose membranes for the adsorption preconcentration of Ni(II), Zn(II), and Cd(II) from aqueous solutions. The binding ...

Abundant published evidence is presented to show the practical utility of the previously developed model of inductive effect for analysis of the reactivity of organic and organoelement compounds. The universal character ...

Studies by 1H NMR spectroscopy and X-ray diffraction analysis revealed hindered rotation of the aromatic substituent about the C Ar-N bond in ortho-substituted (except for o-fluorine-substituted) phosphorus-containing ...

A method of synthesizing arylbisdithiophosphonic acids was developed by the reaction of 2,4-diaryl 1,3,2,4-dithiadiphosphetane-2,4-disulfides with tri(ethylene glycol) and 1,4-butandiol in anhydrous benzene suspension under ...

Using the additivity scheme, experimental enthalpies of vaporization and formation of phosphoranes were analyzed, group contributions to the enthalpies of vaporization and formation were determined, and thermochemical ...
