In organic chemistry, phosphonates or phosphonic acids are organophosphorus compounds containing C−PO(OR) 2 groups, where R is an organic group (alkyl, aryl). If R is hydrogen then the compound is a dialkyl phosphite , which is a different functional group.
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. Phosphinates feature two P–C bonds, with the general formula R 2 P(=O)(OR').
The general formula of a phosphoric acid is H n+2−2x P n O 3n+1−x, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure, between 0 and n + 2 / 2 . Pyrophosphate anion. Trimethyl orthophosphate.
The general structure of an ether. R and R' represent most organyl substituents. In organic chemistry, ethers are a class of compounds that contain an ether group—an oxygen atom bonded to two organyl groups (e.g., alkyl or aryl). They have the general formula R−O−R′, where R and R′ represent the
In organic chemistry, phosphonites are organophosphorus compounds with the formula P(OR) 2 R. ... Oxidation of phosphonites gives phosphonates: 2 P(OR) 2 R + O 2 → ...
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 ...
For example, the formula of methyl phosphate is CH 3-H 2 PO 4, dimethyl phosphate – (CH 3) 2 HPO 4 and trimethyl phosphate – (CH 3) 3 PO 4. Alkyl phosphates are widely distributed in nature, and form the basis of most biological processes. For example, high energy metabolites such as ATP and PEP are alkyl phosphates, as are nucleic acids ...
Triethyl phosphite 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.
