The structure and relative stability of Molybdata-Phosphonic Acid (MP) Complex in different solventshave been carried out using Density Functional Theory (DP[) methods. The methods me used forcalculations are B3LYP and 83PW91. that have been studied in two series of basis sets: D95"and 6-31+0(cl,p) for hydrogen and oxygen atoms; LANL2OZ for Mn and Phosphorus. Predicted geometw and relativestabi...

To create an effective adhesion promotion for different surfaces, specific anchor groups are necessary such as phosphonic metals. Biobased phosphorylated monomer from cardanol was synthesized and polymerized by UV curing or miniemulsion radical polymerization. Phosphonic ethoxy methacrylate (CMP) via hydroxyethylation, followed phosphorylation addition of dimethyl phosphite onto the unsaturatio...

Ammonium molybdate, in acid solution, is reduced to an oxide stage, with the production of a blue color, by many substances of biological importance. Our attention was first attracted to this subject through an accidental observation. We were engaged in the attempt to work out a technique for the nephelometric estimation of phosphoric acid, using a heavy solution of cane sugar for the medium of...

A new spray reagent with copper, ammonium molybdate, and sulphuric acid for the detection of phospholipids on thin-layer chromatograms is described. The specificity and sensitivity of the spray reagent is also shown.

A new way to analyze supramolecular dendritic architectures is reported by making use of (13)C NMR and (31)P NMR. Two ethylene glycol guest molecules have been synthesized containing a (13)C labeled carboxylic acid headgroup (2) and a phosphonic acid headgroup (3). The binding of these guests to urea-adamantyl modified poly(propylene imine) dendrimers has been investigated with (13)C NMR and (3...

A general and efficient phosphorous acid-catalyzed cyclocondensation of β-ketoesters with o-aminobenzamides via selective C-C bond cleavage leading to quinazolinones is developed. This reaction proceeds smoothly under metal- and oxidant-free conditions, giving both 2-alkyl- and 2-aryl-substituted quinazolinones in excellent yields. This strategy can also be applied to the synthesis of other N-h...

A unique 3D Cu(II) complex based on a molybdate oxide cluster and 5-triazole isophthalic acid was synthesized under hydrothermal condition: {Cu(2)(HL)(2)[Mo(4)O(13)]}·2H(2)O (H(2)L = 5-triazole isophthalic acid) (1). Compound 1 shows a spin canting magnetization behavior, and a definite hysteresis loop with a large coercive field of 6.85 kOe.
