실험 절차

11.95 g (34.7 mmol) of tetraisopropyl methylenebisphosphonate, 5.2 g (173.5 mmol) of paraformaldehyde and 2.54 g (34.7 mmol) of dimethylamine are combined with the same reactants and at the same conditions as described above in Example I. This mixture is then refluxed for 117 hours. After the methanol has been eliminated as described above in Example I, 3.0 g of tetraisopropyl ethenylidenebisphosphonate is produced as a clear liquid.
