Method for the preparation of fluorine-containing phosphonates and phosphonic acids |
| abstract |
Fluorine-containing phosphonates and phosphonic acids are described. The method of preparation is a reaction of trialkylphosphites with dihalodifluoromethanes or a reaction of the salts of dialkylphosphites with halodifluoromethylphosphonates. The corresponding phosphonic acids are prepared by hydrolysis of the phosphonates. |
