Phosphonates feature tetrahedral phosphorus centers. They are structurally closely related to (and often prepared from) phosphorous acid. Phosphonate salts are the result of deprotonation of phosphonic acids, which are diprotic acids: RPO(OH)2 + NaOH → H2O + RPO(OH)(ONa) (monosodium phosphonate) … See more In organic chemistry, phosphonates or phosphonic acids are organophosphorus compounds containing C−PO(OR)2 groups (where R = alkyl, aryl, or just hydrogen). Phosphonic acids, typically handled as salts, are generally See more Hydrolysis Phosphonate esters are generally susceptible to hydrolysis under both acidic and basic conditions. Cleavage of the P-C bond is harder but can be achieved under aggressive conditions. O=PC(OR)2 + 2 H2O … See more Phosphonates are one of the three sources of phosphate intake in biological cells. The other two are inorganic phosphate and organophosphates. The naturally occurring phosphonate 2-aminoethylphosphonic acid was first identified in 1959 in … See more In medicine, phosphonates and bisphosphonates are commonly used as inhibitors of enzymes which utilize phosphates and … See more Several methods exist for the preparation of phosphonic acids and their salts. From phosphonic acid Most processes begin with phosphorous acid (aka phosphonic acid, H3PO3), exploiting its reactive P−H bond. Phosphonic acid … See more Bisphosphonates Compounds containing 2 geminal phosphonate groups are known as bisphosphonates. They were first synthesized in 1897 by Von Baeyer and Hofmann and now form the basis for an important class of … See more In 1998 the consumption of phosphonates was 56,000 tons worldwide – 40,000 tons in the US, 15,000 tons in Europe and less than 800 tons in Japan.
