Phosphonate

Phosphonates and phosphonic acids are organophosphorus compounds containing C-PO(OH)2 or C-PO(OR)2 groups (where R=alkyl, aryl). Phosphonic acids and phosphonate salts are typically white, nonvolatile solids that are poorly soluble in organic solvents, but soluble in water and common alcohols. Many commercially important compounds are phosphonates, including Glyphosate, the herbicide "Roundup", and Ethephon, a widely used plant growth regulator. Bisphosphonates are popular drugs for treatment of osteoporosis.〔Svara, J.; Weferling, N.; Hofmann, T. "Phosphorus Compounds, Organic," In 'Ullmann's Encyclopedia of Industrial Chemistry, Wiley-VCH, Weinheim, 2008. .〕
==Basic properties==
Phophonates feature tetrahedral phosphorus centers. They are structurally closely related to (and often prepared from) phosphorous acid.〔Modern Phosphonate Chemistry By Philippe Savignac and Bogdan Iorga, CRC Press,  Boca Raton, FL. 2003. ISBN 0-8493-1099-7.〕
Phosphonate salts are the result of deprotonation of phosphonic acids, which are diprotic acids:
:RPO(OH)2 + NaOH → H2O + RPO(OH)(ONa) (monosodium phosphonate)
:RPO(OH)(ONa) + NaOH → H2O + RPO(ONa)2 (disodium phosphonate)
Phosphonate esters are the result of condensation of phosphonic acids with alcohols.
