Phosphonate - an overview ScienceDirect Topics
WebPhosphonates or phosphonic acids are organic compounds containing C–PO (OH)2 or C–PO (OR) 2 groups (where R = alkyl, aryl). Most phosphonates are highly water soluble, … 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 … See more Phosphonates are one of the three sources of phosphate intake in biological cells. The other two are inorganic phosphate and … See more In medicine, phosphonates and bisphosphonates are commonly used as inhibitors of enzymes which utilize phosphates and diphosphates as substrates. Most notably, these enzymes include those that produce the intermediates of … 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.
