phosphonic

Several methods exist for the preparation of phosphonic acids and their salts.

Since the work of Schwarzenbach in 1949, phosphonic acids are known as effective chelating agents.

It is unsure which of the two possible patways is used to get phosphonic acid.

The stability of the metal complexes increases with increasing number of phosphonic acid groups.

Analysis of glyphosate and (aminomethyl) phosphonic acid in a suspected poisoning case.

Developing safe foliar spraying of phosphonic acid to control peach and apple phytophthora.

A protecting group used for carboxylic acids was adapted to phosphonic acids, making this transformation easy.

Consequently, they hydrolyze to give phosphonic and phosphinic acid derivatives, but not phosphate.

Phosphonates are highly water-soluble while the phosphonic acids are only sparingly so.

Phosphonic esters are prepared using the Michaelis-Arbuzov reaction.

Fosfomycin is a phosphonic acid antibiotic active against gram-positive, gram-negative, and anaerobic bacteria.

Methyl phosphonic dichloride is an organophosphorus compound.

Thionyl chloride converts phosphonic acids and phosphonates into phosphoryl chlorides.

At high pH, sarin decomposes rapidly to nontoxic phosphonic acid derivatives.

Phosphonate esters are the result of condensation of phosphonic acids with alcohols.

They knew of two phosphonic acid compounds that were ineffective against weeds, and the researchers were not able to advance the compounds.

In this version of the drug, the two negative charges of the tenofovir phosphonic acid group are masked, thus enhancing oral absorption.

Organophosphates: Alkylene phosphonic acids.

In the absence of base, however, the reaction produces phosphonic acid and an alkyl chloride, according to the following stoichiometry:

Phosphonic acid can be alkylated under Mannich conditions to give aminomethylated phosphonates, which are useful as complexants.

The phosphonic acid derivative ibrolipim is believed to lower those levels by accelerating fatty acid oxidation.

The synthesis of glycerol-1,3-diphosphonic acid, the phosphonic acid analogue of the naturally occurring glycerol-1,3-diphosphoric acid, is described.

Phosphite (HPO3), or phosphonic acid, has traditionally been used for post-infection treatment of the fungal disease in huge amounts.

The electrophilic character of PCl is highlighted by its reaction with styrene to give, after hydrolysis, phosphonic acid derivatives.

The most important use of phosphorous acid (phosphonic acid) is the production of phosphites (phosphonates) which are used in water treatment.
