Product Name:Diethyl (Tosyloxy)methylphosphonate
English Name:Diethyl (Tosyloxy)methylphosphonate
CAS No.:31618-90-3
Aliases:Diethyl tosyloxymethylphosphonate, (Tosyloxy)methylphosphonic acid diethyl ester, Diethyl ((p-toluenesulfonyloxy)methyl)phosphonate, Diethoxyphosphorylmethyl 4-methylbenzenesulfonate
Molecular Formula:C12H19O6PS
Physical Properties:Colorless to pale yellow viscous liquid. Molecular weight 322.31, density approximately 1.20 g/cm³. Soluble in dichloromethane, chloroform, ethanol, ethyl acetate and other organic solvents; practically insoluble in water. Sensitive to light and moisture; store sealed in a cool place protected from light.
Uses:Used as an organic synthesis intermediate and important raw material for the preparation of α-substituted phosphonates, alkenylphosphonates, and phosphonate-containing pharmaceutical molecules. It also serves as a precursor for Wittig-Horner and HWE reactions for carbon chain extension and functional group transformation.
