Process for making 1-hydrox-ybisphosphonates |
| abstract |
This invention relates to an addition reaction between anions of dialkyl phosphites and acid halides to produce 1-hydroxy-bisphosphonates and substituted hydroxybisphosphonates. It is preferred that this reaction take place at a low temperature in a base so that rearrangement to dialkyl ( dialkoxyphosphinyl) phosphates is minimized. |
