Phosphonates are ubiquitous organophosphorus compounds that contain a characteristic CP bond which is chemically inert and hydrolytically stable. Bacteria have evolved pathways to metabolize these phosphonate compounds and utilize the products of these pathways as nutrient sources. This review aims to present all of the known bacterial enzymes capable of transforming phosphonates to phosphates....

Copper(II) salts have long been used to kill algae in water systems, but they can precipitate as insoluble salts and form deposits on equipment surface. It is important to remove toxic metal from industrial waste because of contamination and toxicity issues. This paper discusses the testing and effects of various phosphonates to control copper-based fouling in the industrial water systems. It h...

Iron(II) and iron(III) salts catalyze the oxidative alpha-phosphonation of N,N-dimethylanilines with dialkyl H-phosphonates in the presence of tert-butylhydroperoxide.

The synthesis of 5' - deoxynucleoside 5' - phosphonates which contains a 5' - CP bond in place of the 5' -COP bond of the naturally occuring nucleotides is described. The preparation of phosphonate derivatives of acyclo - nucleosides and a simple method for the conversion of 1-? -D-ribofuranosyl pyrimidines to the corresponding 1-? -D-arabinofuranosyl pyrimidines are also explained

We report a method for the synthesis of α-diazo-β-keto esters, phosphonates and sulfones via acylation of corresponding diazomethyl anions with N-acylbenzotriazoles. The N-o-amino-acylbenzotriazoles exhibited an unprecedented transphosphorylation reaction leading to diazoacetyl phenylphosphoramidates.

The copper-catalysed oxidative coupling of amines and H-phosphonates to produce phosphoramidates has been achieved using CuI as the catalyst and O2 (present in air) as the sole oxidant.

The interactions of two antiviral, acyclic nucleoside phosphonates, adefovir and cidofovir, with xenobiotic transporters was studied in intact killifish (Fundulus heteroclitus) renal proximal tubules by using fluorescent substrates, confocal microscopy, and quantitative image analysis. Both drugs reduced in a concentration-dependent manner the transport of fluorescein on the classical organic a...

Hollow manganese phosphonate microspheres of an inorganic-organic hybrid with hierarchically porous shells were prepared through a template-free hydrothermal method using ethylene diamine tetra(methylene phosphonic acid) as the coupling molecule. The hollow structures with hierarchical porosity were confirmed by SEM, TEM and N2 sorption. FT-IR, XPS and TG-DSC measurements revealed that the orga...
