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 plants and many animals, where it is localized in membranes. … 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.

Webdiphenyl phosphonate were used in the same reaction. Yao assumed that transesterification of the initial H-phosphonate with Ti(OPr i) 4 should merely shift the equilibrium of two tautomeric forms 3a and 3b toward more active metalloxy phosphite 4 and therefore to favor the nucleophilic addition (Scheme 2). Web4 Phosphonate FRs. Phosphonates 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, while the phosphonic acids are only sparingly soluble. Phosphonates are not volatile and are poorly soluble in organic solvents.
