Process for the preparation of acylaminomethane phosphonic acids |
| abstract |
Acylaminomethanephosphonic acids are valuable intermediates for the production of the herbicide N-phosphonomethylglycine and its salts.n n n According to the invention, acylaminomethanephosphonic acids of the formula (I) R¹-CO-NHCH₂P (= O) (OH) ₂ (I) wherein R¹ is H, C₁-C₆-alkyl, benzyl or optionally substituted phenyl, can be prepared in an industrially usable process, which is characterized by reacting the compound of the formula R¹-CO-NH-CH₂OH with P₂O₃ and subsequent hydrolysis with water. |
