Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Methanol | HCID 887 | — |
| Reactant | Methacrylic Acid | HCID 4093 | — |
| Reactant | Dimethyl methylphosphonate | HCID 12958 | — |

Reaction Steps
108 g of dimethyl methanephosphonate are added dropwise at 70° C. to a solution of 86 g of methacrylic acid and 32 g of methanol in the course of 30 minutes. After a reaction time of 3 hours the reaction mixture is worked up by vacuum distillation. 59 g of 3-(dimethylphosphinyl)-2-methylpropionic acid are obtained with a 91.1% purity, which corresponds to a theoretical yield of 29.5%.
