Glyphosate, part of the herbicide "Roundup", is a phosphonate. 2-aminoethylphosphonic acid: the first identified natural phosphonate. Phosphonates are one of the three sources of phosphate intake in biological cells. [citation needed] The other two are inorganic phosphate and organophosphates.
They exhibit tautomerism, however, the equilibrium overwhelmingly favours the right-hand (phosphonate-like) form: [11] [12] (RO) 2 POH ⇌ (RO) 2 P(O)H The P-H bond is the site of high reactivity in these compounds (for example in the Atherton–Todd reaction and Hirao coupling ), whereas in tri-organophosphites the lone pair on phosphorus is ...
Ammonium phosphonate forms colorless crystals of rhombic system, spatial group C mma, cell parameters a = 0.757 nm, b = 1.147 nm, c = 0.398 nm, Z = 4. [ 5 ] The compound is soluble in water and ethanol , but insoluble in acetone .
They have the general formula R−O−R′, where R and R′ represent the organyl groups. Ethers can again be classified into two varieties: if the organyl groups are the same on both sides of the oxygen atom, then it is a simple or symmetrical ether, whereas if they are different, the ethers are called mixed or unsymmetrical ethers.

Triethyl phosphite (TEP) is an organophosphorus compound, specifically a phosphite ester, with the formula P(OCH 2 CH 3) 3, often abbreviated P(OEt) 3. It is a colorless, malodorous liquid. It is used as a ligand in organometallic chemistry and as a reagent in organic synthesis.
Triethyl phosphonoacetate is a reagent for organic synthesis used in the Horner-Wadsworth-Emmons reaction (HWE) or the Horner-Emmons modification.. Triethyl phosphonoacetate can be added dropwise to sodium methoxide solution to prepare a phosphonate anion.
In organic chemistry, phosphonites are organophosphorus compounds with the formula P(OR) 2 R. They are found in some pesticides and are used as ligands. [1] Preparation
With the formula (HO) 2 P(O)CH 2 NHCH 2 CO 2 H, this derivative of glycine is one of the most widely used herbicides. Bisphosphonates are a class of drugs to treat osteoporosis. The nerve gas agent sarin, containing both C–P and F–P bonds, is a phosphonate. [citation needed] Phosphinates feature two P–C bonds, with the general formula R 2 ...
