HRID 1883241Notes

Reaction equation

P(CN[CH2:7][C:8]([OH:10])=[O:9])(O)(O)=O.[C:11]([NH:14][CH2:15][C:16]([OH:18])=[O:17])(=[O:13])[CH3:12]>>[C:11]([N:14]([CH2:7][C:8]([OH:10])=[O:9])[CH2:15][C:16]([OH:18])=[O:17])(=[O:13])[CH3:12]

Participants

Reactant 2

HCID 3496Glyphosate

HCID 10972Acetylglycine2×

Product 1

HCID 10130190N-acetyliminodiacetic acid

Procedure

The preparation of N-(phosphonomethyl)glycine starting from N-acetglycine XVIII is depicted in Reaction Schemes 13 and 14. In this Reaction Scheme, N-acetglycine XVIII is carboxymethylated to yield N-acetyliminodiacetic acid XVI which is then converted to Glyphosate I as described in Reaction Schemes 6, 7, and 8.

Workup

customis depicted in Reaction Schemes 13 and 14
