1-chloro-2-diethoxyphosphorylethane

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: For example, K. Moedritzer, R. R. Irani, J. Inorg. Nucl. Chem. 22 (1961) 297-304 describes by way of example a process which begins by reacting diethyl β-chloroethylphosphonate with potassium diethyl phosphonate to give tetraethyl ethylenediphosponate, which is then converted into the desired ethylenediphosphonic acid by hydrolysis with concentrated hydrochloric acid.
