Process for the preparation of acylaminomethanephosphonic acids |
| abstract |
Acylaminomethanephosphonic acids are useful intermediates for the preparation of the herbicide N-phosphonemethylglycine and its salts. n According to the invention, acylaminomethanephosphonic acids of the formula (I) n n R.sup.1 --CO--NHCH.sub.2 P(═O) (OH).sub.2 (I) n n in which R 1 is H, C 1 -C 6 -alkyl, benzyl or optionally substituted phenyl, can be prepared in a process which can be employed industrially, which comprises the reaction of the compound of the formula R 1 --CO-NH--CH 2 OH with P 2 O 3 and then hydrolysis with water. |
