Compounds with N - (perfluoracil) - N - fossonometil glycine compound herbicide to control indesejaveis process plants and process for preparing the compounds.

摘要

N-(perfluoroacyl)-N-phosphonomethyl glycine compounds are prepared by the reaction of N-phosphonomethyl glycine with perfluoroacyl anhydrides employing an excess of the perfluoroalkanoic acid as the solvent. The N-(perfluoroacyl)-N-phosphonomethyl glycine compounds are useful as post-emergent herbicides.
