The preparation of vinylphosphonic acid compounds (I) by reacting phosphorous acid compounds (II) with acetylene is carried out in the presence of palladium(0) (Pd(0)) complexes or corresponding platinum (Pt) complexes with bidentate ligands (III) as catalyst. The preparation of vinylphosphonic acid compounds of formula (I) by reacting phosphorous acid compounds of formula (II) with acetylene is carried out in the presence of palladium(0) (Pd(0)) complexes or corresponding platinum (Pt) complexes with bidentate ligands of formula (III) as catalyst. R<1>, R<2> = hydrogen (H), 1-16 carbon (C) alkyl, 6-12 C aryl, 7-12 C alkaryl or 7-12 C aralkyl, optionally mono- or poly-substituted by halogen, hydroxyl, acyl or acetoxy; X = ferrocenylene or 1-6 C alkylene (optionally interrupted with oxygen (O), sulfur (S) or imino (NR'') in the chain; R'' = H, 1-6 C alkyl, 6-12 C aryl, 7-13 C alkaryl, 7-13 C aralkyl or 5-8 C cycloalkyl; R = 1-12 C alkyl, 6-12 C aryl, 5-8 C cycloalkyl, 7-13 C aralkyl, 7-13 C alkaryl or 7-16 C alkoxyaryl; or 2 R attached to one phosphorus (P) atom = 5-8 C alkylene or 6-10 C cycloalkylene. An Independent claim is also included for the use of the Pd(0) or corresponding Pt complexes in the preparation of (I).
