    摘要: A process for preparing vinylphosphonic acid compounds of the formula (I) where R1 and R2 are, independently, H, C1-16-alkyl, C6-12-aryl, C7-12-alkaryl or C7-12-aralkyl, it being possible for the organic radicals to be substituted by one or more halogen atoms, hydroxyl, acyl or acetoxy groups, by reacting phosphorous acid compounds of the formula (II) with acetylene in the presence of a Pd(O) complexe or Pt(O) complex as catalyst.
