Synthesis in high vacuum and synthesis in the absence of solvent: Two new options for obtaining β-styryl phosphonic acid
(Instituto de Investigación de las Ciencias Exactas Físicas y Naturales, 2007-05-13)
Terminal olefins allow the addition of phosphorus pentachloride to give substances that can be considered as phosphonic acid chlorides. Hydrolysis transforms the addition products in phosphonic acids, usually with simultaneous ...
Critical micelle concentration of tridecane, tetradecane and hexadecane phosphonic acids and their mono- and disodium salts
(Elsevier Science, 2009-12)
The critical micelle concentration (CMC) of tridecane, tetradecane and hexadecane phosphonic acids and their mono- and disodium salts were determined with a battery of methods. The CMC values for all the studied species ...
Hydrophosphorylation of aliphatic alkynes catalyzed by CuNPs/ZnO for the synthesis of vinyl phosphonates: a DFT study on the reaction mechanism
(Royal Society of Chemistry, 2017-03)
The reaction mechanism of the CuNPs/ZnO-catalyzed hydrophosphorylation of aliphatic alkynes for the synthesis of vinyl phosphonates has been investigated. Based on experimental observations and theoretical calculations ...
Complete assignment of H-1 and C-13 NMR spectra of some 4 '-substituted diethyl 1-methylthio- and diethyl 1-methylsulfonyl-2-oxo-2-phenylethylphosphonates

Inversion Properties of n-Alkane Phosphonic Acids Stabilized Emulsions: HLB Dependence
(Taylor, 2009-11-29)
The emulsifier properties of n-alkane phosphonic acids (C10H21PO3H2; C12H25PO3H2 and C13H27PO3H2) and their mono- and di-sodic salts were studied, with emphasis on the morphological and dynamical inversion properties as a ...
New insights into the chemistry of gem-bis(phosphonates): Unexpected rearrangement of Michael-type acceptors
(Wiley VCH Verlag, 2005-08)
The use of tetraethyl ethylidenebis(phosphonate) as a Michael acceptor with different nucleophiles was investigated. It was found that in some cases this compound undergoes phosphate removal, depending on the nature of the ...
