Phosphonic acid: preparation and applications
The phosphonic acid functional group, which is characterized by a phosphorus atom bonded to three oxygen atoms (two hydroxy groups and one P=O double bond) and one carbon atom, is employed for many applications due to its structural analogy with the phosphate moiety or to its coordination or supramolecular properties. Phosphonic acids were used for their bioactive properties (drug, pro-drug), f...
متن کاملA Density Functional Theory Study of Structure of Phosphonic Acid
The molecular structure of the stable conformation of phosphonic acid in gas phase has beencomputed by employing complete geometry optimization in Density Functional Theory(DFT) methods. The methods used for calculations are B3LYP, BP86 and B3PW91 that havebeen studied in two series of basis sets: D95** and 6-31+G(d,p) for hydrogen and oxygenatoms; LANL2DZ for phosphorus. Bond lengths and angle...
متن کاملGraphene phosphonic acid as an efficient flame retardant.
We report the preparation of graphene phosphonic acid (GPA) via a simple and versatile method and its use as an efficient flame retardant. In order to covalently attach phosphorus to the edges of graphene nanoplatelets, graphite was ball-milled with red phosphorus. The cleavage of graphitic C-C bonds during mechanochemical ball-milling generates reactive carbon species, which react with phospho...

Z. Naturforsch. 50b, 855-858 (1995); received November 11, 1994 Organophosphonic Acid Anhydrides, Phosphonic Acid Anhydrides, Stereochemistry, NMR Spectra The phosphonic acid anhydrides of the general formula [R P 0 2]„ have been prepared with R = Me, Et, z-Pr, r-Bu, and Ph from the corresponding phosphonic acids and their chlorides and esters. Mass spectrometric data indicate that the trimers ...
متن کاملSynthesis and biological evaluation of phosphonic and thiophosphoric acid derivatives of lysophosphatidic acid.
Using an N-oleoyl ethanolamide scaffold, a series of phosphate polar head group analogues of LPA comprised of various alpha-substituted phosphonates and thiophosphates was prepared. In a broken cell GTP[gamma35S] binding assay, agonist activity was evaluated at the three LPA receptors of the endothelial differentiation gene (Edg) family. This study has resulted in the discovery of a nonhydrolyz...
