Versuchsvorschrift

1-Phosphono-1,2-ethane-dicarboxylic acid can be prepared by reaction of maleic ester (diethyl maleate) with diethyl phosphite in the presence of sodium alcoholate followed by acid saponification of the ester. 2-Phosphono-2,3-propane dicarboxylic acid can be obtained in the same manner with addition of the step of reacting the mixture with methyl chloride before the saponification step.
